Akyol, Sinem; Alatas, Bilal
Classical optimization algorithms are insufficient in large scale combinatorial problems and in nonlinear problems. Hence, metaheuristic optimization algorithms have been proposed. General purpose metaheuristic methods are evaluated in nine different groups: biology-based, physics-based, social-based, music-based, chemical-based, sport-based, mathematics-based, swarm-based, and hybrid methods which are combinations of these. Studies on plants in recent years have showed that plants exhibit intelligent behaviors. Accordingly, it is thought that plants have nervous system. In this work, all of the algorithms and applications about plant intelligence have been firstly collected and searched. Information is given about plant intelligence algorithms such as Flower Pollination Algorithm, Invasive Weed Optimization, Paddy Field Algorithm, Root Mass Optimization Algorithm, Artificial Plant Optimization Algorithm, Sapling Growing up Algorithm, Photosynthetic Algorithm, Plant Growth Optimization, Root Growth Algorithm, Strawberry Algorithm as Plant Propagation Algorithm, Runner Root Algorithm, Path Planning Algorithm, and Rooted Tree Optimization.

Özkaya, Ferhat Can; Peker, Zerife; Camas, Mustafa; Camas, Anil Sazak; Altunok, Muhammet
Ethyl acetate extracts from 70 strains of marine-derived fungi, isolated from sponges, were screened against four fish pathogenic bacteria. Sixteen of the fungal isolates exhibited antibacterial activity against at least one pathogen. All the strains showed antibacterial activity against Vagococcus salmoninarum. Three isolates showed strong inhibition against all test pathogens and they may therefore be remarkable as a broad-spectrum antimicrobial. Nine isolates showed antibacterial activity against Lactococcus garvieae, six were against Vibrio anguillarum, and four isolates inhibited the growth of Yersinia ruckeri. Co-culture of the fungus with the mix of the pathogen bacteria led to the induction of bioactivity in two isolates. Aspergillus iizukae produced strong and broad-spectrum antibacterial activity against pathogens with minimum inhibitory concentrations of 0.8-406 mu gmL(-1). The screening results confirmed the sponge associated fungi as a source of environmentally friendly antimicrobials that may contribute the sustainable development of aquaculture. In addition, co-culture technique is a promising strategy to increase antimicrobial activity that can stimulate the production of novel compounds, and increases the antimicrobial activities of marine derived fungi.

Bayrakdar, Cihan; Çilgin, Zeynel; Saris, Faize
Karadag is one of the mountains subjected to the Pleistocene glaciations in the Teke Peninsula (Western Taurus) along with Beydaglari, Akdag, and Sandiras Mountains. Karadag, which reaches 2418 m summit at a 30 km straight distance from the northeast of Fethiye Bay, has many peaks over 2300 m. There are plenty of glacial researches and dating studies aim to reveal Pleistocene glaciation chronology of the mountains such as Sandiras and Akdag in the Teke Peninsula. On the other hand, glaciations in Beydaglari were mentioned superficially and in general terms. Lastly, there has not been known any glaciation phenomenon in Karadag, in other words there are not any studies concerning the glaciation on the mountain. However, Karadag has distinctive cirques and moraines on the slopes of high elevations near the peak. In this study, we identified glacial valleys, cirques developed in different sizes and aspects and lastly frontal and hummocky moraines in front of these cirques. They are descending to the elevation of 1800 m. With this study, a new glacial area was identified in Turkey and made a contribution to the glaciation inventory of Turkey. This study aims to reveal the geomorphological and climatological characteristics of this area with regard to tectonic, climatic and karstic characteristics during Pleistocene. Maps and relevant outputs were created and analyzed by geographic information systems using the spatial data obtained from the field studies, unmanned aerial vehicles and meteorological stations.

Aydin, Ali; Korkmaz, Sengul Aslan; Demir, Veysel; Tekin, Saban
Background: In cancer, apoptosis relevant proteins-such as CaM kinase, Bcl-2 or P53, topoisomerase I, cell migration feature and DNA/BSA-macromolecules represent significant targets for current chemotherapeutics. Objective: We recently reported two coordination compounds-[Cu(C6H16N2O2)(2)][Ni(CN)(4)] (1) and [Cu(C6H16 N2O2) Pd(CN)(4)] (2)-together with their IR spectra, magnetic properties, thermal analyses and crystal structures. Herein, we describe the ability of these complexes to induce apoptosis in relevant proteins and stimulate topoisomerase I activity, cell migration velocity and DNA/BSA binding properties. Method: The in vitro antiproliferative effects and cell toxicity of both compounds were investigated through pharmacological measurement techniques, and interactions between both compounds and CT-DNA/BSA were studied with UV-Vis spectroscopy and fluorescence spectroscopy. Results & Conclusion: Studies on cells revealed that 2 (i) demonstrated a high antiproliferative effect, which was higher toward HeLa and C6 cancer cells than toward healthy Vero cells; (ii) impaired the migration of HeLa cells; (iii) altered the P53-Bcl-2 ratio in favor of apoptosis; (iv) strongly bound to DNA/BSA macromolecules; and (v) inhibited human topoisomerase I and KpnI or BamHI restriction endonucleases. In conclusion, this preliminary information demonstrates that 2 may represent a promising antiproliferative agent and a potential candidate for a therapeutic approach against HeLa.

Esen, Yuksel; Dogan, Zulfu Murat
The objective of this study is to investigate the usability of siderite aggregates mentioned above as a heavy-weight aggregate in the heavy-weight concrete production and their effects on physical properties of the heavy-weight concrete mixture. For this purpose, normal-weight aggregate content was decreased at the rate of 20%, 40%, 60%, 80% and 100% by volume of the concrete mixture prepared and mixtures were prepared by its substitution with siderite aggregate at the same rates. Based on the increase in siderite aggregate in the concrete mixture, a considerable increase in unit weight, compressive strength and tensile strength of concrete was obtained. Plate-shaped concrete specimens obtained from combined normal-weight and heavy-weight aggregates were exposed to radiation with different X-ray source (118 keV, 164 keV) and Co-60 (1250 keV) beam source at cekmece Nuclear Facility. It is clearly seen that the concrete mixture containing siderite aggregate improved 70% radiation absorption characteristics compared to that of the concrete mixture without siderite aggregate.

Sonmez, Feray; Kutlu, Banu; Sesli, Ahmet
The environmental factors that affect the seasonal change of the phytoplankton community and composition in Karkamis Dam Lake were investigated on samples taken from five stations between January 2015 and December 2015. It was found that the phytoplankton of Karkamis Dam Lake consisted of 85 taxa belonging to Bacillariophyta (56 taxa), Chlorophyta (15 taxa), Chrysophyta (1 taxon), Cyanophyta (10 taxa), Dinophyta (2 taxa) and Euglenophyta (1 taxon). Members of Bacillariophyta and Chrysophyta increased well during spring, summer and also at the end of fall whilst Chlorophyta grew well only in summer and fall. Cyanophyta became dominant at the end of spring and in summer. However Dinophyta was remarkably conspicuous in winter as well as in spring and fall in terms of prevalence. Excessive reproduction of Cyanobacteria, which is a characteristic aspect of mesotrophic lakes, was observed in Karkamis Dam Lake in both May and July. Results of physical and chemical measurements and analysis indicated that the lake was mesotrophic based on PCA and Carlson trophic state index. Phytoplankton composition was found to be affected by environmental factors such as temperature, pH, dissolved oxygen, phosphate and nitrate through the year. Using these data, a strong model was developed for sustainable management in Karkamis Dam Lake.

In the present study was determined the effects of monthly variability on enzymatic antioxidant (superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px)), antioxidant (reduced glutathione (GSH)) and the oxidant status (nitric oxide (NO), lipid peroxidation (MDA)) in hepatopancreas, muscle, gills and gonad tissues of freshwater crayfish (A. leptodactylus) the monthly collected throughout the year from Keban Dam Lake of Turkey. Results indicate that variations in oxidants and antioxidants with relation to month were not only tissue specific but also were gender specific. The levels of oxidant parameters were generally higher in hepatopancreas in comparison to muscle, gills and gonad of crayfish. Moreover, in tissues were also determined the different oxidants and antioxidants responses in moulting, mating, breeding and egg laying periods.

Nas, Mehmet Salih; Gür, Aycan; Gür, Tugba; Yönten, Vahap
The thermodynamic parameters and immobilization kinetics of catalase enzyme via adsorption onto krill clay were performed in aqueous solution in batch system. The adsorbent was characterized by X-ray fluorescence, scanning electron microscope and Brunauer-Emmett-Teller N-2 adsorption measurements. The effect of some parameters to the adsorption process such as contact time, stirring speed, initial enzyme concentration, initial ionic strength, temperature and pH were analyzed. Maximum adsorption capacity (q(m)) showed a great dependence on pH and initial enzyme concentration. It was found at pH 5.5, and initial enzyme concentration, 0.0075 g L-1 values. Pseudo-first-order, pseudo-second-order and intraparticle diffusion were used to fit the kinetics data on kinetic models. Furthermore, thermodynamic activation parameters such as enthalpy, entropy, Gibbs free energy and activation energy (Delta H degrees, Delta S degrees, Delta G degrees and E-a) which reveal that catalase enzyme adsorption occur spontaneously and in endothermic nature were determined. The obtained results confirmed that the applicability of krill clay is an efficient immobilizing supporter for catalase enzyme and krill clay material can be used as a very effective adsorbent in immobilization of this enzyme from aqueous solutions.

Zinc nanoparticles (ZnNPs) are among the least investigated NPs and thus their toxicological effects are not known. In this study, tilapia (Oreochromis niloticus) were exposed to 1 and 10 mg/L suspensions of small size (SS, 40-60 nm) and large size (LS, 80-100 nm) ZnNPs for 14 days under semi-static conditions. Total Zn levels in the intestine, liver, kidney, gill, muscle tissue, and brain were measured. Blood serum glucose (GLU), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), and lactate dehydrogenase (LDH) were examined to elucidate the physiological disturbances induced by ZnNPs. Organ pathologies were examined for the gills, liver, and kidney to identify injuries associated with exposure. Significant accumulation was observed in the order of intestine, liver, kidney, and gills. Zn levels exhibited time- and concentration-dependent increase in the organs. Accumulation in kidney was also dependent on particle size; NPs SS-ZnNPs were trapped more effectively than LS-ZnNPs. No significant accumulation occurred in the brain (p>0.05) while Zn levels in muscle tissue increased only marginally (p0.05). Significant disturbances were noted in serum GOT and LDH (p<0.05). The GPT levels fluctuated and were not statistically different from those of controls (p>0.05). Histopathological tubular deformations and mononuclear cell infiltrations were observed in kidney sections. In addition, an increase in melano-macrophage aggregation intensity was identified on the 7th day in treatments exposed to LS-ZnNPs. Mononuclear cell infiltrations were identified in liver sections for all treatments. Both ZnNPs caused basal hyperplasia in gill sections. Fusions appeared in the gills after the 7th day in fish treated with 10 mg/L suspensions of SS-ZnNPs. In addition, separations in the secondary lamella epithelia were observed. The results indicated that exposure to ZnNPs could lead to disturbances in blood biochemistry and cause histopathological injuries in the tissues of O. niloticus. (c) 2016 Wiley Periodicals, Inc.

Polat, R.; Cakilcioglu, U.; Selvi, S.; Türkmen, Z.; Kandemir, A.
In this study, we comparatively investigated three endemic Salvia species spreading in Erzincan (Turkey) in terms of anatomy and micromorphology. For anatomical investigation, cross sections taken from stems and leaves of the species were examined under light microscope. For micromorphological investigation, epidermal surface and nutlet structure were examined using scanning electron microscopy. The S. euphratica and S. divaricata species were examined anatomically and micromorphologically for the first time, and S. hypargea was examined micromorphologically for the first time. In anatomical examinations, it was seen that stem and leaf structures of the species were similar. In micromorphological analyses, it has been seen that hairiness of the nutlet surface and nutlet ornamentations (verrucate and rugose type) created a difference between the species.

Akkoyunlu, Atilla; Avsar, Yasar; Erguven, Gokhan Onder
The objective of this study is to analyze the time processes of hazardous waste management (HWM) in Turkey. There should be a holistic evaluation of a country's hazardous waste management program in terms of theoretical qualifications, best practice applications, and, of course, problems and their solutions. This paper offers a similar approach to evaluate HWM in compliance with the European Union under the laws of environmental applications. In 2010, 786,418 tons of hazardous waste (HW) were produced in Turkey. Of this, around 18% is sent to municipal garbage dumps, 0.6% is burned, and the remaining 81.4% is disposed of by other methods (such as controlled landfill or haphazard throwaways).
