Öğe The effects of compost prepared from waste material of banana on the growth, yield and quality properties of banana plants(Triveni Enterprises, 2005) Doran, I; Sen, B; Kaya, ZThree doses (15-30-45 kg plant(-1)) of the compost prepared from the clone of Dwarf cavendish banana were compared with farmyard manure (50 kg plant), mineral fertilizers (180 g N+ 150 g P +335 g K plant(-1)) and farmyard manure+ mineral fertilizers (25 kg FM+ 180 g N + 150 g P+335 g K plant(-1)) which determined positive effects on the growth, yield and fruit quality of banana plants. The banana plants were grown under a heated glasshouse and in a soil with physical and chemical properties are suitable for banana growing. The contents of N, P, K and Mg in compost and in farmyard manure were hound to bee similar. Farmyard manure, farmyard manure + mineral fertilizers and 45 kg plant(-1) of compost increased growth, yield and fruit quality characteristics. According to obtained results, 45 kg plant(-1) of compost was determined more suitable in terms of economical production and organic farming than the other fertilizer types.Öğe The effects of compost prepared from waste material of banana plants on the nutrient contents of banana leaves(Triveni Enterprises, 2003) Doran, I; Sen, B; Kaya, ZIn this study, the possible utilization of removed shoots and plant parts of banana as compost after fruit harvest were investigated Three doses (15-30-45 kg plant(-1)) of the compost prepared from the clone of Dwarf Cavendish banana were compared with Farmyard manure (50 kg plant(-1)), Mineral fertilizers (180 g N+150 g P+335 g K plant(-1)) and Farmyard manure + Mineral fertilizers (25 kg FW+180 g N+150 g P+335 g K plant(-1) which determined positive effects on the nutrient contents of banana leaves. The banana plants were grown under a heated glasshouse and in a soil with physical and chemical properties suitable for banana growing. The contents of N, P, K and Mg in compost and in farmyard manure were found to be similar. Nitrogen, phosphorus and potassium contents of leaves in all applications except control, and Ca, Mg, Fe, Zn, Mn, Cu contents in all applications were determined between optimum levels of reference values. There were positive correlations among some nutrient contents of leaves, growth, yield and fruit quality characteristics. Farmyard manure, Farmyard manure + Mineral fertilizers and 45 kg plant(-1) of compost increased the nutrient contents of banana leaves. According to obtained results, 45 kg plant(-1) of compost was determined more suitable in terms of economical production and organic farming than the other fertiliser types.Öğe Effects of farmyard manure and chemical fertilizers on the nutritional status of the loquat trees.(Triveni Enterprises, 2003) Doran, I; Kaya, Z; Caglar, SThe nutritional status of the loquat trees was investigated using cattle manure and commercial fertilizers for three years. The farmyard manure increased N, P, K, Mg, Fe and Zn contents of the leaves. No significant difference was found between the fertilizer types for trunk growth. Yield efficiency was nearly doubled by application of farmyard manure. Fertilizers did not affect the weight and shape of the fruits; however, commercial fertilizers If the lower total acidity in fruits. It was concluded that,the loquat trees grown in sandy soils could fulfill their principal nutrient requirements for growth and commercial yield with application of farmyard manure.Öğe Effects of N-acetylcysteine on pulmonary function in patients undergoing coronary artery bypass surgery with cardiopulmonary bypass(Sage Publications Ltd, 2003) Eren, N; Çakir, Ö; Oruc, A; Kaya, Z; Erdinc, LCardiopulmonary bypass (CPB) has been implicated in causing poor pulmonary gas exchange postoperatively in patients undergoing coronary artery bypass grafting (CABG) procedures. In this prospective, randomized, double-blind, placebo-controlled study, we examined the pulmonary effects of N-acetylcysteine (NAC) in patients undergoing CABG. Twenty patients undergoing elective CABG and early tracheal extubation were randomized into two groups. Group I (ten patients) received a physiologic salt solution as a placebo in a continuous intravenous infusion for one hour before CPB and 24 hours after CPB; Group II (ten patients) received 100 mg/ kg NAC intravenously for one hour before CPB and 40 mg/kg/day at 24 hours after CPB. Perioperative hemodynamic and pulmonary data were recorded. Postoperative tracheal extubation was accomplished at the earliest appropriate time. The postoperative clinical course was similar in the two groups. Both groups exhibited significant postoperative increases in A-a oxygen gradient (p < 0.01), but patients in Group II exhibited significantly lower increases in postoperative A-a oxygen gradient (p < 0.006). Other hemodynamic and pulmonary data (pulmonary capillary wedge pressure, pulmonary vascular resistance (PVR), cardiac index (CI), shunt flow, dynamic lung compliance and static lung compliance) exhibited no differences between the groups. There was no significant difference in terms of intubation time. The malondialdehyde (MDA) increase in Group II following CPB was found to be significantly lower than in Group I (p = 0.043). This clinical study reveals that administration of NAC to patients undergoing elective CABG with CPB improves systemic oxygenation. There was no effect in other pulmonary parameters and in terms of intubation time.Öğe Foreign body asphyxiation in children(Indian Academy Pediatrics, 2005) Goren, S; Gurkan, F; Tirasci, Y; Kaya, Z; Acar, KWe aimed to investigate the frequency and epidemiological features of deaths due to foreign body asphyxiation (FBA) in childhood, over 1990-2003. Of the victims, 14 (63.6%) were male and 8 (36.4%)females. The mean age of the victims was 2.2 +/- 0.6 years. There were 20 (90.9%) children between 1 and 3 years, and two other cases at 2112 and 5 years of ages. All aspirations had occurred at home. Eight (36.4%) of the victims were dead on arrival, 11 (50%) on intervention, and 3 (13.6%) after complications. Food material was the most commonly aspirated foreign body in 81.8% of the cases, nuts being the most common (50%). Food asphyxiation remains a common problem particularly in children between I and 3 years of age in our region. These fatal accidents can be prevented by parental education and early recognition and management of the situation.Öğe Proteolytic activity of commercial subtilisin from genus Bacillus on some animals milk caseins(Mbr Press Inc, 1997) Aytekin, C; Kaya, Z; Dogru, MCasein is a non-specific substrate for the all proteases. In this study casein was purified from cow, water buffalo, sheep and goat milk and used as a substrate for subtilisin purified preparations from genus Bacillus. On the basis of K-M and V-max value we can say that cow milk casein is the best substrate for the enzyme compared to other animals milk caseins. On the other hand, we have investigated the possible relationship between the Ca2+ and (PO4)(3-) content of casein and the casein appropriate for the enzyme. The cow milk casein with lowermost Ca2+/(PO4)(3-) ratio suggests that these ions may have an influence on enzyme-substrate interaction. Although this enzyme is active in the pH range of 7-11 and a temperature range of 25-60 degrees C, the optimal pH and temperature for the enzyme against cow milk casein were found to be 10,0 and 37 degrees C respectively.
