Effects of some igrs on greenhouse whitefiles (trialeurodes vaporariorum westfood (hom.: aleyrodidae)

220C±2 sıcaklık, % 49±5 oransal nem ve 14:10 (A: K) aydınlanma kosullarına sahip laboratuvarda böcek gelisim düzenleyicileri, Lufenuron (Lufenox, Sygenta, 100cc/100 l); Diflubenzuron (Dimilin, Cansa, 20gr/100 l); Pyriproxyfen (Admiral, Sumitomo, 50cc/100l) ve Neem Azal T/S (Trifolio-M, 4 l/100 l, Lahnau/ Germany)’ ın, sera beyazsinegi, Trialeurodes vaporariorum (Hom.: Aleyrodidae)’ a karsı bulasık domates, Lycopersicum esculentum var. M–16 ve L. esculentum var. Jadelo, bitkileri üzerinde etkileri denenmistir. Her iki ilaçlama sonucunda denemeye alınan ilaçların laboratuvar kosullarında sera beyazsinegi larvaları üzerinde anlamlı bir etkiye sahip olmadıkları anlasılmıstır. Sadece 2. uygulama denemesinde söz konusu zararlıya ruhsatlı olan Admiral isimli IGR’ ın düsük bir etkisi saptanabilmistir. Dolayısıyla sera beyazsinegi gibi zararlılara karsı böcek gelisim düzenleyicileri kullanılacagı zaman, baskı altına alınabilme süreçlerini daha kısa ve ekonomik hale getirebilmek amacıyla baslangıçta etki süresi kısa, seçici bir sentetik insektisitin en düsük dozunda uygulanması ve sonraki uygulamalarda böcek gelisim düzenleyicilerin programa alınması son derece yararlı olacaktır.Insect growth regulators, Lufenuron (Lufenox, Sygenta, 100cc/100 l); Diflubenozuron (Dimilin, Cansa, 20gr/100 l); Pyriproxyfen (Admiral, Sumitomo, 50cc/100l) and Neem Azal T/S (Trifolio-M, 4 l/100 l Lahnau/ Germany,), were tested for their effect against the greenhouse whitefly Trialeurodes vaporariorum (Westwood) (Hom.: Aleyrodidae) on infested tomato, Lycopersicum esculentum var. M–16 and L. esculentum var. Jadelo plants in the laboratory under 22±2 0C, 49±5% relative humidity, and 14 hours day-length conditions. As a result of the study, all IGRs have not caused significant effect on Trialeurodes vaporariorum in the labrotuary conditions. Only in second application it was found that the Admiral which is registered on whitefly has low effect on Trialeurodes vaporariorum. In conclusion, when IGRs are used; to make the pressure period shorter and cheaper, applying a low-dosage synthetic insecticide having a short effect at the begining and including IGRs in following applications will be more useful

Convergent double coronary sinus potentials during atrial tachycardia

The analysis of the patterns and timing of coronary sinus activation provides a rapid stratification of the most likely macro-re-entrant atrial tachycardias and points toward the likely origin of centrifugal ones by comparing the left atrial and coronary sinus activation sequence and morphology during sinus rhythm and atrial tachycardia. The analysis of both the near- and far-field electrogram morphology of atrial signals also gives important clues in determining the mechanism of the arrhythmia

Evaluation of nutritional status in pediatric intensive care unit patients: the results of a multicenter, prospective study in Turkey

IntroductionMalnutrition is defined as a pathological condition arising from deficient or imbalanced intake of nutritional elements. Factors such as increasing metabolic demands during the disease course in the hospitalized patients and inadequate calorie intake increase the risk of malnutrition. The aim of the present study is to evaluate nutritional status of patients admitted to pediatric intensive care units (PICU) in Turkey, examine the effect of nutrition on the treatment process and draw attention to the need for regulating nutritional support of patients while continuing existing therapies.Material and MethodIn this prospective multicenter study, the data was collected over a period of one month from PICUs participating in the PICU Nutrition Study Group in Turkey. Anthropometric data of the patients, calorie intake, 90-day mortality, need for mechanical ventilation, length of hospital stay and length of stay in intensive care unit were recorded and the relationship between these parameters was examined.ResultsOf the 614 patients included in the study, malnutrition was detected in 45.4% of the patients. Enteral feeding was initiated in 40.6% (n = 249) of the patients at day one upon admission to the intensive care unit. In the first 48 h, 86.82% (n = 533) of the patients achieved the target calorie intake, and 81.65% (n = 307) of the 376 patients remaining in the intensive care unit achieved the target calorie intake at the end of one week. The risk of mortality decreased with increasing upper mid-arm circumference and triceps skin fold thickness Z-score (OR = 0.871/0.894; p = 0.027/0.024). The risk of mortality was 2.723 times higher in patients who did not achieve the target calorie intake at first 48 h (p = 0.006) and the risk was 3.829 times higher in patients who did not achieve the target calorie intake at the end of one week (p = 0.001). The risk of mortality decreased with increasing triceps skin fold thickness Z-score (OR = 0.894; p = 0.024).ConclusionTimely and appropriate nutritional support in critically ill patients favorably affects the clinical course. The results of the present study suggest that mortality rate is higher in patients who fail to achieve the target calorie intake at first 48 h and day seven of admission to the intensive care unit. The risk of mortality decreases with increasing triceps skin fold thickness Z-score

For determining pre-service teachers' attitude towards concept maps, 5 point likert Concept Map Attitude Scale" was used. For evaluating their concept mapping skills, without any restriction, they were requested to compose a concept map about the issue that they know best about science. Concept maps were evaluated according to a rubric. Data that obtained from attitude scale and charts data, were analyzed with quantitative methods. According to these results with gender aspect, attitudes towards the concept map show meaningful diff erence for girls; skills results were in men's favour but insignifi cant. In respect to class level, attitude of junior students and skills of senior students show meaningful diff erence. In point of efficacy perception, pre-service teachers who have enough knowledge about drawing concept map, both attitudes and skills, showsignifi cant diff erence

Rhamphomyia (Lundstroemiella) cimrmani Barták (Figs 9–13) Rhamphomyia cimrmani Barták, 2006: 504. Material examined. 35 ♂, 18 ♀, Turkey, Mugla University campus, 710 m, MT, 37 °09' 39 ''N, 28 ° 22 ' 20 ''E, xi.– iii. 2013, M. Barták & Š. Kubík leg. Specification of male characters. Frons with 1–2 pairs of setae on lower part; length of antennal segments = 7–13: 5–8: 46–50: 7–8; 14–18 acrostichals; postpronotum with 0–1 longer (often black) seta and 8–16 pale somewhat shorter setae; notopleuron with pale or dark setae in front part; laterotergite with pale setae or with several black setae intermixed; wing measurements: M 2 /d = 1.3–1.5, CuA 1 ratio = 2.0– 2.4, lw:ww = 2.8–3.3; abdominal sternite 1 with several pale setae; hypandrium with 4–7 setulae; length of body 2.9–4.3 mm, wing 3.0– 3.8 mm. Description of female. Face shorter and broader than in male, about 0.15 mm long and 0.12 mm broad ventrally (at broadest point). All facets nearly equal in size. Occiput with somewhat shorter setae than in male. Labrum twice as long as height of head. Thorax as in male, only setae much shorter, both acrostichals and dorsocentrals about 0.10–0.15 mm long (only slightly longer than distance between rows of acrostichals and dorsocentrals). Hind basitarsus 4 times as long as broad. Abdomen more lustrous than in male, tergites 5–6 polished at least on posterior half, also lateral parts of preceding tergites more or less lustrous, first and last three tergites and all sternites microtrichose. Lateral parts of tergites 2–3 with setae about 0.15 mm long, setae on distal segments shorter, dorsum of abdomen with much shorter setae. Length of body 3.9–4.3 mm, wing 3.0– 3.4 mm. Remarks. Rhamphomyia (L.) cimrmani was originally described from a single male specimen. Findings of additional materials enabled us to give more precise specification of male characters including their variations. Female is described here for the first time and images of both male and female including genitalia are added. There are three species of the subgenus Lundstroemiella with microtrichose mesoscutum and long dark mesoscutal setae at least in males, viz. R. longefilata, R. cimrmani and R. granadensis Chvála. The last species differs from both former by broad frons in male and microtrichose abdomen in female (see key in Barták 2006). Differences between males: frons in R. longefilata is about as long as broad and lustrous at least in dorsal half but about 2–2.5 times as long as broad and entirely microtrichose in R. cimrmani; face in R. cimrmani is about as long as frons but twice as long as frons in R. longefilata; abdomen in R. longefilata is more lustrous and longer setose dorsally than in R. cimrmani; R. longefilata has hypandrium with at most two short setae and cercus about as long as high, whereas R. cimrmani has hypandrium with many setae and cercus about twice as long as high. Female of R. longefilata has lustrous frons and R. cimrmani entirely microtrichose.Published as part of Barták, Miroslav, Kubík, Štěpán, Civelek, Hasan Sungur & Dursun, Oktay, 2014, New species of Rhamphomyia (Diptera: Empididae) from Turkey with a key to species of the Middle East and adjacent territories in Zootaxa 3815 (1), DOI: 10.11646/zootaxa.3815.1.4, http://zenodo.org/record/22745
