A telemetry antenna system for unmanned air vehicles

This paper presents a low VSWR high gain telemetry antenna system manufactured for UAVs that provides 360± coverage in the roll plane of the UAV. Proposed telemetry antenna system includes four telemetry antennas, one power divider that has one input and four output terminals which feeds the telemetry antennas with equal magnitude and phase. Proposed high gain telemetry antennas are based on the feeding of the microstrip patch antenna via aperture coupling. Full coverage in the roll plane of the UAV is obtained by using circular array configuration of telemetry antennas. RF power divider is designed by using couple of Wilkinson power dividers with equal line lengths and impedance sections from input terminal to the all four output terminals

Angioedema due to Systemic Isotretinoin Therapy

Angioedema is the swelling of the mucosal membranes as a variant of urticaria induced by hereditary C1 esterase inhibitor enzyme deficiency, certain foods, or drugs. Herein, we report the case of a 23-year-old woman, with mild-moderate acne presenting with widespread facial angioedema on the 2nd day of systemic isotretinoin treatment. The patient had taken no drugs other than isotretinoin in the preceding days and had no known food allergy. Her angioedema was resolved after the isotretinoin was discontinued. We want to draw the attention of dermatologists to this rare adverse allergic effect of isotretinoin which is frequently used in the treatment of acne vulgaris

Optimization of aperture coupled microstrip patch antennas

Aperture coupled microstrip patch antennas (ACMPA) are special class of microstrip antennas with high gain and wide impedance bandwidth. These antennas differ from other microstrip antennas with their feeding structure of the radiating patch element. Input signal couples to the radiating patch through the aperture that exists on the ground plane of the microstrip feedline. These special antennas are multilayer stacked type of antennas with so many design variables that will affect the antenna performance. This paper presents the design and optimization procedure of ACMPA while taking care of all possible design variables and parameters to get the highest possible antenna gain and minimum VSWR

Comparison of the effect of naproxen, etodolac and diclofenac on postoperative sequels following third molar surgery: a randomised, double-blind, crossover study

Objectives: To compare the three non-steroidal anti-inflammatory agents (NSAIDs) diclofenac potassium, etodol - ac and naproxen sodium in relation to pain, swelling and trismus following impacted third molar surgery. Study Design: The study was a randomized and a double-blinded study which included 42 healthy young individu - als with impacted third molars and bone retention. Patients were randomly assigned to 3 groups (n: 14) to which diclofenac potassium, naproxen sodium and etodolac were administered orally an hour before the operation. Im - pacted third molars were surgically extracted with local anaesthesia. Visual analog scales (VAS) were used to assess the pain in the 6 th , 12 th hours and on the 1 st , 2 nd , 3 rd , 5 th , and 7 th days postoperatively. Swelling was evaluated using ultrasound (US) and mouth opening (trismus) was measured with a composing stick pre and post operatively on the 2 nd and 7 th days respectively. Results: Regarding pain alleviation, diclofenac potassium was better than naproxen sodium and naproxen sodium was better than etodolac but these differences were not statistically significant. US measurements showed that the swelling on postoperative 2 nd day was significantly lowest with diclofenac potassium as compared to others (p= 0.027) while naproxen sodium and etodolac acted similarly (p=0.747). No difference was noted regarding trismus in any of the groups. Conclusions: NSAIDs (diclofenac, naproxen and etodolac) are somehow similarly effective for controlling pain and trismus following extraction of mandibular third molars but diclofenac potassium surpasses others in reduc - tion of swellin

Öğretmen Adaylarının Öğretmenlik Mesleğine Yönelik Tutumları (İnönü Üniversitesi, Eğitim Fakültesi Örneği)

This study intends to determine the attitudes of the students in the faculty of education towards profession of teaching. To this end, it is questioned whether “the attitudes of students towards the profession of teaching differ according to the variables including their gender, the type of the department/program they study, the order of the program in the UEE (University Entrance Examination) preference list, the socio-economic status (SES) of the neighborhood and family they live in, the grade they attend, type of schooling, and the reasons for choosing teaching profession”. The participants of the study comprise 593 students who are selected using rated cluster sampling method for the departments and rated element sampling method for the classes. All of the prospective teachers participating this study were administered the instrument for data collection. The instrument used to collect data in this study was the “Attitude Scale towards the Profession of Teaching”, a single-dimension Likert type scale with 5 points, originally developed by Üstüner (2006). A significant difference was observed between the attitudes of prospective teachers with intrinsic motivations towards the profession of teaching and those of latter teachers with extrinsic motivations towards the profession of teaching. Other variables for which significant differences were observed include gender, the type of the department/program they study, the order of the program in the UEE (University Entrance Examination) preference list, and the socio-economic status (SES) of the neighborhood and family they live in.Bu çalışmanın amacı, eğitim fakültesi öğrencilerinin öğretmenlik mesleğine yönelik tutumlarını belirlemektir. Bu amaçla “öğrencilerin öğretmenlik mesleğine yönelik tutumlarının; adayların cinsiyetleri, okumakta oldukları bölüm/programın türü, ÖSS’de tercih sıraları, yaşadıkları çevre, ailenin sosyoekonomik düzeyi (SED), kaçıncı sınıfta oldukları, öğrenim türü ve öğretmenlik mesleğini tercih nedenleri değişkenlerine göre farklılık gösterip göstermediği” sorularına yanıt aranmıştır.

Efficacy and safety of mascara dyeing as an adjunct to Alexandrite and Nd:YAG laser applications for removing thin and white-colored facial and axillary hair

WOS: 000391344600010PubMed ID: 27762642Introduction: There is no satisfactory and efficient method for long-term removal of white-colored and thin hair. Methods: We conducted a randomised clinical trial of hirsute patients with excessive white and/or thin hair on the face and/or axilla. In Group I (n: 16), the facial hair on one side of the face was painted with a black eyelash mascara immediately before Nd:YAG laser and the other half was only treated by Nd:YAG. In Group II (n: 20), the axillary hair on one side was painted with the mascara before the Alexandrite laser with the other side being only treated by Alexandrite. Results: The terminal hair counts on the painted facial and axillary sides were significantly lower than those on the control sides throughout the study except for the first month. The decrease in the terminal hair count was significant from the beginning of treatment to the second and sixth months on the painted and control facial sides and to the first and sixth months on the axillary sides. Conclusion: Hair coloring with black eyelash mascara is a simple, efficient and safe adjunct to Alexandrite and Nd:YAG laser applications to enhance their clinical efficacy in eliminating white and thin facial or axillary hair

Effects of dietary black cumin (Nigella sativa L.) oil on growth performance, hemato-biochemical and histopathology of cypermethrin-intoxicated Nile tilapia (Oreochromis niloticus)

This study was conducted to investigate the effects of dietary black cumin (Nigella sativa L.) oil on growth performance, hemato-biochemical, and histopathology of cypermethrin-intoxicated Nile tilapia. After determining the LC50 (96 h) value of cypermethrin, cypermethrin was added to the water at a ratio of 1:20 of this concentration, and the fish were fed for 42 days. To reduce the effects of cypermethrin, 1% black cumin oil was added to the fish feed as a potential protectant. Growth parameters, hematology, blood biochemistry, and histopathological changes of Nile tilapia were examined after the feeding period. In this study, the best growth was observed in the group fed with feed containing 1% black cumin oil, while the worst growth performance was observed in the group fed with water containing cypermethrin and without black cumin oil in the feed. As a result of the study, it was observed that black cumin oil added to the fish diet reduced the negative effects of water-borne cypermethrin on growth, hematology, blood biochemistry, and histopathological parameters of Nile tilapia

The Effects of Exogenous Glutamine Application on Some Germination Parameters of Different Carrot Cultivars Grown in Salinity Conditions

Carrot (Daucus carota), which can be orange, yellow, purple, white and red in color due to the difference in the pigments it contains, is a very rich food in terms of carotene and ascorbic acid. In this study, the effects of exogenous Glutamine (Gln) pre-treatments ( 1, 2, 3, 4 mM) on the some germination parameters of carrot seeds (orange, yellow, purple), which are known to be sensitive to salt stress according to the cultivar, were investigated under salt stress conditions (150 mM NaCl). For this purpose, germination percentage (GP), mean germination time (MGT), germination rate coefficient (CVG), germination rate index (GRI), germination index (GI), which are some of the important germination parameters, were determined. According to the results of analysis of variance, it was determined that there was an interaction between cultivars and applications and all germination parameters under salt stress conditions (***plt%253B0.001). The effect of Gln pre-treatments on germination under salt stress and unstressed conditions differed according to the application dose and cultivar. Glutamine application under salt stress had no effect on germination except for the orange carrot cv. In this cultivar, 1 mM pre-treatment had a positive effect on germination parameters under salt stress conditions. In unstressed conditions, although 3 mM Gln pretreatment in orange carrot cv. and 4 mM Gln in yellow carrot cv. had a positive effect on germination parameters compared to control, the highest germination in purple carrot cv. was obtained in control seeds
