Studies On The Anion Recognition Properties Of Synthesized Receptors Iii: A Novel Thiourea-Based Receptor Constructed By Benzo-15-Crown-5 For Sensing Anions In A Strong Polar Solvent, You-Ming Zhang, Hai-Xian Ren, Yan-Qing Zhou, Rong Luo, Wei-Xia Xu, Tai-Bao Wei
Turkish Journal of Chemistry
A new series of receptors were designed and synthesized, and their interactions with anions, such as F^-, Cl^-, Br^-, I^-, CH_3COO^-, HSO_4^-, and NO_3^-, in DMSO solvent were investigated using UV-Vis absorption spectroscopy. The results showed that hydrogen-bonding complexes were formed between the receptors and the tested anions, such as CH_3COO^- and F^-. It was also found that the selectivity of the receptors for anions could be efficiently tuned by changing the place of the substituent group at the N-phenyl moiety. The recognition mechanism and binding mode are discussed. These findings were expected to be of significance for designing and …

Role Of Tridentate Schiff Base And Methoxyethylindenyl Derivatives Of Lanthanocene Complexes For The Synthesis Of High Molecular Weight Polymethyl Methacrylate (Pmma), Muhammad Yousaf, Aftab Ahmad Chatha, Abdul Jabbar, H. Badaruddin Ahmad, Ameer Fawad Zahoor, Muhammad Kaleem Khosa, Syed Sarwar Alam
Turkish Journal of Chemistry
Different mixed ligand lanthanocene complexes along with Al(i-Bu)_3 are capable of synthesizing partially syndiotactic high molecular weight polymethylmethacrylate. The Schiff base derivative of mixed ligand lanthanocene complexes (1-4) showed better efficiency (Mv = 227 \times 10^3-354 \times 10^3) compared to the methoxyethylindenyl derivative of mixed ligand lanthanocene complexes (5-9) (Mv = 72 \times 10^3, 172 \times 10^3). The effects of the catalyst, temperature, catalyst/MMA molar ratio, and catalyst/Al(i-Bu)_3 molar ratio on the polymerization of MMA at 60 °C suggested that ligand size and radius of rare earth metals play an important role in determining the activity of the catalyst.

Floral Biology, Breeding System, And Pollination Ecology Of Cucurbita Moschata (Duch. Ex Lam) Duch. Ex Poir. Varieties (Cucurbitaceae) From Parts Of The Niger Delta, Nigeria, Ikechukwu Ozoemenam Agbagwa, Benjamin Chinyem Ndukwu, Stephen I. Mensah
Turkish Journal of Botany
Flowering, breeding mechanisms, and pollination biology of Cucurbita moschata (Duch. ex Lam) Duch. ex Poir. varieties were studied. C. moschata carries male and female flowers on the same plant and is pollinated by thrips and bees with nectar and pollen as major rewards for the pollinators. Both flowers begin opening between 0330 and 0400 hours. The male flower opens for about 8 to 9 h and the female opens for 6 h 30 min to 7 h. There is, however, a period of overlap in the flower anthesis of both sexes, which coincides with the peak of pollen viability and …

Efficacy Of Solanum Villosum Mill. (Solanaceae: Solanales ) As A Biocontrol Agent Against Fourth Instar Larvae Of Culex Quinquefasciatus Say, Nandita Chowdhury, Indranil Bhattacharjee, Subrata Laskar, Goutam Chandra
Turkish Journal of Zoology
Dried ground leaves of Solanum villosum, Mill. were extracted with 5 different solvents [petroleum ether, benzene, choloform:methanol (1:1 v/v), acetone, and absolute alcohol] to determine the best extractant for subsequent isolation and characterization of larviciding compounds. Each batch of larvae (10 per batch) was treated with 30 ppm, 50 ppm, and 100 ppm of each extract in 3 replicates. All eluted fractions were found to induce significant mortality in test mosquito species. The petroleum ether eluted fraction was the least toxic, whereas the chloroform:methanol (1:1 v/v) eluted fraction was the most toxic to the larvae. A very high mortality rate …

A Review Of Studies In Swarm Robotics, Levent Bayindir, Erol Şahi̇n
A Review Of Studies In Swarm Robotics, Levent Bayindir, Erol Şahi̇n
Turkish Journal of Electrical Engineering and Computer Sciences
Swarm robotics is a new approach to the coordination of large numbers of relatively simple robots. The approach takes its inspiration from the system-level functioning of social insects which demonstrate three desired characteristics for multi-robot systems: robustness, flexibility and scalability. In this paper we have presented a preliminary taxonomy for swarm robotics and classified existing studies into this taxonomy after investigating the existing surveys related to swarm robotics literature. Our parent taxonomic units are modeling, behavior design, communication, analytical studies and problems. We are classifying existing studies into these main axes. Since existing reviews do not have enough number of …

Aggregation, Foraging, And Formation Control Of Swarms With Non-Holonomic Agents Using Potential Functions And Sliding Mode Techniques, Veysel Gazi̇, Bariş Fi̇dan, Y. Si̇nan Hanay, İlter Köksal
Turkish Journal of Electrical Engineering and Computer Sciences
In this article we consider the aggregation, foraging, and formation control of swarms whose agents are moving in 2-dimensions with non-holonomic unicycle agent dynamics. We approach these problems using artificial potentials and sliding mode control. The main contribution is extension of the recent results (mainly for aggregation) in the literature based on a similar approach for simple integrator agent dynamics models to a significantly more realistic and more difficult setting with non-holonomic unicycle agent dynamics models. In particular, we design continuous-time control schemes via a constructive analysis based on artificial potential functions and sliding mode control techniques. The effectiveness of …

Aggregation In Swarm Robotic Systems: Evolution And Probabilistic Control, Onur Soysal, Erki̇n Bahçeci̇, Erol Şahi̇n
Turkish Journal of Electrical Engineering and Computer Sciences
In this study we investigate two approachees for aggregation behavior in swarm robotics systems: Evolutionary methods and probabilistic control. In first part, aggregation behavior is chosen as a case, where performance and scalability of aggregation behaviors of perceptron controllers that are evolved for a simulated swarm robotic system are systematically studied with different parameter settings. Using a cluster of computers to run simulations in parallel, four experiments are conducted varying some of the parameters. Rules of thumb are derived, which can be of guidance to the use of evolutionary methods to generate other swarm robotic behaviors as well. In the …
Swarm Robot Systems Based On The Evolution Of Personality Traits, Sidney Nascimento Givigi Jr.
Swarm Robot Systems Based On The Evolution Of Personality Traits, Sidney Nascimento Givigi Jr.
Turkish Journal of Electrical Engineering and Computer Sciences
Game theory may be very useful in modeling and analyzing swarms of robots. Using game theory in conjunction with traits of personalities, we achieve intelligent swarm robots. Traits of personality are characteristics of each robot that define the robots' behaviours. The environment is represented as a game and due to the evolution of the traits through a learning process, we show how the robots may react intelligently to changes in the environment. A proof of convergence for the proposed algorithm is offered. The process of selection of traits is discussed and the potential of the modeling is demonstrated in several …
