An Interface Design for Axial Induction Motor

Asynchronous motors have been used extensively in the industry since the first discovery. Although the general working principles do not change, they can be made geometrically in the form of cylinders, spheres, cones and even discs. One of these geometries is known as axial flux machine topology which has a disc structure. Axial flux machines are remarkable in terms of their high efficiency, high power density and advantage in terms of compact structures. In this study, extended literature search of axial flux induction motor is given. In addition to the literature, axial induction motor design interface has been created by using MATLAB GUI software. This interface can communicate with ANSYS Maxwell. Thus, the dimensioning values of the machine calculated via the interface can be drawn automatically in Ansys Maxwell and it can perform numerical analysis. The obtained torque, current and efficiency data were evaluated

Lethal effect of Turkish diatomaceous earth (Bgn-1 ) agaınst adults of German cockroaches (Blatella germanıca L.): Presentation

In this study, mortality effects of BGN-1 which is local diatomaceous earths, were investigated against adults of German cockroach (Blatella gemanica (L.)) on concrete, ceramic floor tile and laminate flooring. On these three different surfaces, B. germanica adults were exposed to BGN-1 diatomaceous earth at the doses of 2.5, 5, 10, 20 g/m2 along 6 days. In all surface applications of BGN-1 diatomaceous earth, exposure time and dose caused significant effect on mortality rates of B. germanica adults. It was determined that BGN-1 coded Turkish diatomaceous earth has the lowest mortality effect on all application surfaces at the dose of 2.5 g/m2. 2.5 g/m2 BGN-1 caused 100 % mortality after 6 days concrete surface and caused 100 % mortality at the end of the fourth day on ceramic floor tile and laminate flooring. On the other hand, doses of 5 and 10 g/m2 of BGN-1 caused 100% B. germanica mortality on all surfaces at the end of the second day, while the highest dose of 20 g /m2 of BGN-1 reached 100% B. germanica mortality at the end of the first day on all application surfaces. In general, the mortality activity of BGN-1 diatomites against B. germanica adults was found to be similar on all three surfaces. At the end of this study, local diatomaceous earth coded BGN-1 was found to be good alternatives for controlling B. germanica which is a medical pest insect

Determınatıon of toxıcıty of gaseous ozone agaınst adult stages of German Cockroach (Blatella germanıca L.): Poster

In this study, the effects of two different concentrations of ozone gas (16.7 and 33.3 mg / L) against Blatella germanica adults at different exposure times (10, 20, 30, 40 and 50 minutes) were investigated under laboratory conditions. It was determined that the ozone gas had a noticeable effect on mortality of B. germanica adults. In general, ozone gas caused higher paralyisis-mortality rates of B. germanica adults than mortality rates of B.germanica adults at both concentrations and all exposure times. A concentration of 33.3 mg / L of ozone gas with 40 and 50 minute exposure times killed all cockroach adults after 24 hours. On the other hand, 16.7 mg / L concentration of ozone gas with 50 minute exposure time killed 90% of the B. germanica adults after 24 hours. When ozone gas is evaluated in terms of exposure time to B. germanica adults, the concentration of 33.3 mg / L of ozone gas with 10-20 minute exposure times caused 65 % adult mortality, with 30 minute exposure time caused 90% adult mortality and with 50 minute exposure times caused 100 % adult mortality after 24 hours. At a concentration of 16.7 mg / L of ozone gas, as the exposure times increased, the adult mortalities gradually increased after 24 hours and the adult mortality reached 90% with 50 minute exposure times. All these results show that ozone gas (33.3 mg / L) with 40-50 minute exposure times can successfully control B.germanica adults.In this study, the effects of two different concentrations of ozone gas (16.7 and 33.3 mg / L) against Blatella germanica adults at different exposure times (10, 20, 30, 40 and 50 minutes) were investigated under laboratory conditions.

Naturally existing Beauveria on the surface of stored wheat kernels, and their pathogenicity on Rhyzopertha dominica and Sitophilus oryzae adults: Poster

Entomopathogenic fungi have been investigated to control stored product pests, as an alternative strategy to chemical insecticides. Although many studies evaluated isolates from various sources, few studies surveyed fungi naturally infecting stored product pests, revealing predominantly Beauveria isolates. This study aimed to reveal the amount of Beauveria carried on the surface of stored wheat kernels, and their pathogenicity against Rhyzopertha dominica and Sitophilus oryzae adults. Sixteen wheat samples from different storage facilities in four cities were examined for existence of Beauveria. One-hundred g of wheat was washed in 100 mL of 2% Tween80 solution. After increasing concentration of possible fungi by centrifugation, the liquid was spread on medium with dodine and monitored at 25±2°C. Nine of the isolates were tested for pathogenicity at 500 ppm (w/w) at 25±2°C, 65±5% r.h. in darkness with five replicates. While only four samples did not have Beauveria, others had 17-2992 cfu/100 g wheat. Six samples had 17-50, four samples 150-858, one sample 1625 and one had 2992 cfu/100 g wheat. Mortalities against R. dominica adults ranged between 5-86% and 32-100% in 7 and 14 days, respectively. Mortality of S. oryzae ranged from 3-45% and 8-83% in 7 and 14 days, respectively. This study demonstrated that wheat kernels can naturally carry Beauveria with various levels of pathogenicity. Potential naturally occurring entomopathogenic fungi can be isolated directly from stored commodities to be evaluated as biological control agents for stored product pest control.Entomopathogenic fungi have been investigated to control stored product pests, as an alternative strategy to chemical insecticides.

Efficiency of ozone gas treatment against Plodia interpunctella (Hübner) (Lepidoptera:Pyralidae) (Indianmeal Moth) in hazelnut: Poster

In this study, ozone gas at different concentrations (16.7, 33.3 and 66.6 mg/L) were exposed to all biological stages (egg, larva, pupa and adult) placed at top and bottom of the hazelnut for various exposure periods (2, 4 and 6 hours). In biological tests conducted in presence of hazelnuts, 100% mortalities of all biological stages of P. interpunctella placed at top of the commodity were obtained at tested ozone concentrations and exposure periods while it was easier to kill the adult and pupa stages that the larva and egg stages. While it was possible to kill 100% of the adults and pupae placed at bottom of the commodity at tested ozone concentrations and exposure periods, 100% mortality of the larvae and eggs were not obtained at any of the ozone treatments. Generally, the mortalities of all life stages of P. interpunctella placed at bottom of the commodity for ozone treatments were lower than those placed at top of the commodity. It was easy to kill the pupae and adults of P. interpunctella placed at bottom of the commodity while the ozone treatments resulted in low mortalities of the egg and larvae placed at bottom of the commodity. Just as 100% mortalities of the larva and adult stages were not obtained even at the highest ozone concentration for the longest exposure period. In conclusion, in this study, it was observed that ozone gas only at high concentrations can control all biological stages of P. interpunctella in hazelnut and therefore could have an alternative potential for methyl bromide in quarantine applications in short application period.In this study, ozone gas at different concentrations (16.7, 33.3 and 66.6 mg/L) were exposed to all biological stages (egg, larva, pupa and adult) placed at top and bottom of the hazelnut for various exposure periods (2, 4 and 6 hours).

Measurement of primary hemostasis potential with platelet function analyzer to investigate the predictive effect on post-operative blood loss in cyanotic and acyanotic pediatric patients

Aim: To investigate hemostatic parameters, including primary hemostasis potential in twenty pediatric patients with or without cyanosis undergoing cardio-pulmonary bypass (CPB) and cardiac surgery to repair congenital defects. Methods: The platelet function analyzer is an instrument that provides a rapid, in vitro, quantitative measurement of platelet adhesion and aggregation in whole blood flowing through a small aperture under high shear conditions. Other parameters monitored included blood loss, prothrombin time, anti-thrombin 3 activity, and fibrinogen and D-dimer levels. Additionally, hematocrit and albumin levels were monitored to assess the level of hemodilution during CPB. Results: Both, cyanotic and acyanotic pediatric patients had evidence of supranormal primary hemostasis potential. Although, measurements in cyanotic patients exhibited a higher percentage ratio, this was found to be statistically insignificant between cyanotic and acyanotic patients (collagen-epinephrine p=0.07 and, collagen and adenosine diphosphate (ADP) p=0.248). While, in preoperative period, measurements of primary hemostasis potential, coagulation and fibrinolytic system parameters demonstrated no statistically significant difference between cyanotic and acyanotic patients, measurement of prothrombin time, international normalized ratio and thrombin time levels significantly changed in cyanotic patients, after the operation (p<0,05). Longer cardio-pulmonary bypass time in cyanotic patients could be responsible for this indifference. Conclusion: The results of our study suggest that the platelet function analyzer system may be an indicator that it can predict bleeding in the postoperative period

Preliminary Checking of Some Turkish Diatomaceous Earth Similarities with Commercial Diatomaceous Earths under Scanning Electron Microscope (SEM)

Diatoms are dead bodies of unicellular algae’s and made up of fossilized diatoms in aquatic ecosystems. Diatomaceous earth (DE) is a dust varying in color depending on composition, from white-grey to yellow to red and active ingredient is amorphous silicon dioxide. DEs are commonly used for purification of water, the purification of juices, separation of various oils and chemicals and also used as an insecticide. Mode of action as insecticide which damage occurs to the insects protective wax coat on the cuticle, mostly by sorption and to a lesser degree by abrasion, or both. The result is the loss of water from the insect's body through desiccation resulting in death. The efficacy of DE against insects depends on different physical and morphological characteristics of the diatoms. In present study, image properties of 10 different Turkish DE samples under Scanning Electron Microscope (SEM) were checked and compared similarities with commercial DEs, namely Protector, SilicoSec, Insecto and Pyrisec. SEM image analysis indicated that there were variations in shape and size of dead bodies of diatoms in Turkish and commercial DEs. The shapes of dead bodies of diatoms in Turkish local DE’s named as CBN and BGN were found very similar with those in commercial DE, Silicosec. Local DE coded as DC has a round shape and looks similar to commercial DE of Pyrisec while local DE coded as CAN has triangle shape and its shape was different from those of all other DE samples

Teachers' Attitudes Toward the Use of Technology in Social Studies Teaching

Technology integration in education is one of the most popular topics in the last decades. Many countries have invested millions of dollars to equip classrooms with technological devices. As well as developed countries, Turkey has conducted several projects to provide technological devices and educational materials to classrooms. Technology has the potential to increase the quality of learning and teaching process. However, having technological devices in classroom alone will not cause the increase of the quality of education. Thus, the purpose of this study is to examine teachers' attitudes toward the use of technology in social studies teaching. Understanding social studies teachers' attitudes is essential because it is a way to figure out how they integrate technology and define barriers. The authors applied quantitative survey method and used cluster sampling to choose participants. The sample of the study consisted of 155 social studies teachers who are currently teaching at middle schools. The use of technology in social studies teaching attitude scale was used to collect data. The findings revealed that teachers have positive beliefs and attitudes toward the use of technology. Also, the findings showed that teachers who are working at private schools have significantly high attitudes than others who are teaching at public schools. Moreover, teachers who took educational technology and teaching material course and attended in-service training have more positive attitudes than others

Use of caffeic acid phenethyl ester and cortisone may prevent proliferative vitreoretinopathy.

PURPOSE: To investigate whether caffeic acid phenethyl ester (CAPE) and cortisone prevent proliferative vitreoretinopathy (PVR). METHODS: Twenty pigmented rabbits were used in this study. All rabbits except controls received an intravitreal injection of 0.15 ml (75,000 U) of platelet-rich plasma into their left eye. The animals were divided into four groups: group I was treated with intraperitoneal injection of 0.5 ml (15 micromol/kg) of CAPE for 3 days, group II received 0.15 ml (4 mg/kg) of intravitreal cortisone, group III received nothing (blank group), and group IV (control group) received only 1 ml of 1% ethanol intraperitoneally daily for 3 days. Proliferative changes were graded in a masked fashion by indirect ophthalmoscopy for a 15-day follow-up period. The malondialdehyde (MDA), reduced glutathione (GSH) and total nitrite (NO) levels were measured in the vitreous humor. RESULTS: The grades of PVR were B-C in group I, and C-D in group II. The PVR grade in the control group was C-D. The mean MDA level in group I (4.0+/-0.8 micromol/l) was significantly lower than in the blank group (6.0 micromol/l) (p < 0.05). The mean GSH level in group I (71.0+/-11.2 micromol/l) was significantly different than in the blank group (p < 0.05). The MDA and GSH levels in group II were 4.7+/-0.6 micromol/l and 53.8+/-7.8 micromol/l, respectively. Both these levels were not significantly different from the blank group (p > 0.05). The NO levels in both treatment groups were significantly lower than in the blank group (p < 0.001). CONCLUSION: These findings suggest an inhibitory effect of CAPE on PVR. The inhibitory effect was supported by lower MDA and NO with higher GSH levels in treatment groups than in the blank group. There was no detected significant effect of cortisone for preventing PVR experimentally
