Gul, Muhammet; Celik, Erkan; Akyuz, Emre
Risk assessment is vital for cost-effective ship management in maritime industry since numerous maritime activities pose potential hazards according to the human causalities. Therefore, safety practitioners attempt to offer proactive approaches to mitigate risk as much as possible. In this context, this article presents a hybrid risk-based approach for maritime industry by adopting Fuzzy Analytic Hierarchy Process (FAHP) with fuzzy VIKOR (FVIKOR) methods under Fine-Kinney approach. To illustrate the hybrid risk-based approach, ballast tank maintenance process is handled since there are various hazards causing fatalities, severe injuries, and illness during ballast tank maintenance procedure than any other type of shipboard work. An extensive risk analysis is performed to enhance environment safety and operational reliability in maritime industry. Besides its theoretical contribution, the outcomes of the paper contribute to improve overall safety level of ship by considering potential hazards in risk management.

Ince, Muharrem; Ince, Olcay Kaplan; Asam, Eren; Önal, Ali
The present study investigated Cu(II) ion adsorption onto banana peel, chestnut shell, and tea leaf waste in aqueous medium under different experimental conditions. Batch adsorption studies were carried out with various Cu(II) concentrations as well as the influence of process parameters such as pH, contact time, and adsorbent amount on the removal of copper, and the optimum conditions for maximum removal of copper from an aqueous solution. These food waste biomass adsorbents were applied to mineral water and industrial wastewater samples and the copper removal potentials were compared. The nature of the adsorbents and metal ion interactions was examined by the fourier transform infrared spectroscopy (FTIR) technique. The adsorption data were obtained by using the Langmuir model showing maximum adsorption capacity of banana peel, chestnut shell, and tea leaf waste at 1.94 mg g-1 2.25 mg g-1, and 3.36 mg g-1, respectively. Copper was determined by flame atomic absorption spectrometry.

Can, Umit; Alatas, Bilal
Nature-inspired metaheuristic algorithms have been recognized as powerful global optimization techniques in the last few decades.Many different metaheuristic optimization algorithms have been presented and successfully applied to different types of problems. In this paper; seven of newest metaheuristic algorithms namely, Ant Lion Optimization, Dragonfly Algorithm, Grey Wolf Optimization, Moth-Flame Optimization, Multi-Verse Optimizer, Sine Cosine Algorithm, and Whale Optimization Algorithm have been tested on unconstrained benchmark optimization problems and their performances have been reported. Some of these algorithms are based on swarm while some are based on biology and mathematics. Performance analysis of these novel search and optimization algorithms satisfying equal conditions on benchmark functions for the first time has given important information about their behaviors on unimodal and multi-modal optimization problems. These algorithms have been recently proposed and many new versions of them may be proposed in future for efficient results in many different types of search and optimization problems.

Interdisciplinary research has revolutionized the field of medicine and we have witnessed exponential increase in the high-impact research in past few decades. However, the road to this burgeoning research field is obstacle-ridden because of intratumor heterogeneity, loss of apoptosis and dysregulation of spatio-temporally controlled signaling pathways. Ground-breaking findings obtained through genetic, genomic and proteomic studies have considerably improved our concepts related to the complexity of protein network and excitingly, discovery of miRNAs has added another layer of intricacy to quantitatively regulated gene networks. In this review, we chronicle the milestone achievements and discuss how Pterostilbenes effectively regulated different cellular pathways. We have provided detailed mechanistic insights related to regulation of JAK-STAT signaling, Notch pathway, Wnt mediated intracellular signaling by pterostilbene. Underlying mechanisms about regulation of PI3K/AKT and MAPK pathways by pterostilbene in different cancers. Regulation of Metastasis-associated protein 1 (MTA1) proteins and Human telomerase reverse transcriptase (hTERT) in cancer cells by pterostilbene. Pterostilbene has also been reported to modulate the expression of various oncogenic and tumor suppressor microRNAs in cancer cells. Better and sharper comprehension of the concepts associated with the modes of action of pterostilbene in different cancers will be useful in identification of cancers which can be efficiently targeted by pterostilbene.

Goksu, Ali; Tanaydin, Mehmet Kayra
Almond shells are classified as an agricultural waste of the food industry. In this study, almond shells were prepared as efficient adsorbents for removing Crystal Violet (CV) dye. The effects of adsorbent dosage, pH, initial concentration, shaking speed, temperature and particle size were studied. The Taguchi L25 experimental design method was used to obtain the optimum experimental condition. The data were analyzed using the signal to noise (S/N) ratio and analysis of variance (ANOVA) for removal of CV from aqueous solutions. The isotherm data were obtained from the experiments performed. The obtained isotherm data were analyzed via the Langmuir, Freundlich and Temkin isotherm models of which the Langmuir isotherm model fitted the best. Thermodynamic parameters such as ΔH°, ΔS° and ΔG° were calculated and the results were 18.5 kJ/mol, 0.057 kJ/mol K and –1.514 kJ/mol at 25°C, respectively. The results of this study indicate that almond shells are efficient adsorbents for removing Crystal Violet (CV) from aqueous solutions. The maximum adsorption capacity was found to be 1.075 mg/g on the almond shells. Adsorption kinetics studies showed that adsorption data can be modeled by a pseudo-second-order model. The optimum conditions for the adsorption on almond shells were found to be: adsorbent dosage = 0.5 g, concentration = 4 ppm, pH = 6, shaking speed = 200 rpm and shaking time = 180 min.

Geç Elizabeth Döneminde sosyo-politik çatışmalar görülmüştür. Bu çatışmalar başta bölük pörçük olmasına rağmen, yavaş yavaş Elizabeth rejimine karşı duyulan toptan bir muhalefet tavrını oluşturmuştur. Ancak, sansür mekanizmasının varlığı ile hukuk sisteminin devletin baskı araçları olarak kullanılmasından dolayı bunlar bastırılmıştır. Bu bağlamda, haklı gerekçelerle yapılan kamuya açık idamlar toplumu rahatlatabilirdi. Ne var ki, teatral olan kamuya açık idamlardaki yargılamaların baştan sağma olmaları, Elizabeth sahnesinin içinde/dışında toplumsal rahatlama sağlayamamıştır. Bu durum, özellikle, Shakespeare’in İlk Dörtlemesi’nde (1589-1594 civarı) kendini göstermiştir. Bundan dolayı, bu makalenin amacı yürütme erki uygulaması olarak kamuya açık idamların politika ve poetika’sını incelemek ve tiyatrolarda bununla ilgili gösterilen sahnelerin gelişigüzel yargılamalardan dolayı oluşan toplum gerginliğini azaltmadığını, aksine, Geç Elizabeth Dönemi’ndeki bu gerginliği arttırdığını örneklemektir.

Çullu, Mustafa; Ertas, Haydar
The aim of this study is to determine the radiation absorption capacity of concretes produced from lead mine waste which cannot be processed economically as the lead content is low in the mines they are extracted. Lead mine waste (tallow) were exchanged at ratios of 25%, 50% and 75% respectively with barite and limestone aggregates and samples were prepared at C16, C25 and 05 classes. The compressive strength and the unit weight of the prepared samples were determined. The linear absorption coefficients of prepared concrete samples at 662 keV of energy were determined. In addition the relationship between the radiation absorption capacity and the compressive strength-unit weight was investigated. The experiments demonstrated that best absorption was in concrete samples with 100% barite content (100B). On the other hand in the concrete samples prepared from the mixture of limestone and lead mine waste aggregates, it was observed that radiation absorption capacity decreased due to decreasing amount of barite. In concrete samples prepared from the mixture of lead mine waste and limestone aggregates, it was observed that radiation absorption capacity increased due to increasing amount of mine waste aggregates in the concrete. As a result it was observed that lead mine waste aggregates do not absorb as much radiation as barite aggregates depending on the ratio increase of lead mine waste in the aggregate added to the concrete mixture. However the absorbed radiation amount was observed to be higher compared to limestone aggregates. (C) 2016 Elsevier Ltd. All rights reserved.

Aksu, O.; Kutluyer, F.; Can, E.; Erisir, M.; Benzer, F.
Stocking density causes changes in behaviour and physiology of aquatic animals and high density can cause oxidative damage in living cells. Therefore, experiments were designed to investigate the effects of stocking density on the oxidant-antioxidant response (glutathione (GSH), glutathione peroxidase (GSH-Px), catalase (CAT), and malondialdehyde (MDA)), digestive enzyme activity (trypsin), and heat shock protein 70 (HSP70) of narrow clawed crayfish (Astacus leptodactylus). The experiment was conducted to assess effects by stocking 3, 6, 9 and 12 crayfish/m(2). Crayfish were stocked into 12 fiberglass tanks, three replicates per treatment and fed for 45 days. Our results indicated that activity of GSH-Px, MDA, and GSH levels increased in hepatopancreas (p<0.05) and muscle tissues (p<0.05) with increasing stock concentration while CAT activity decreased (p<0.05). Trypsin and HSP70 insignificantly increased in haemolymph. In conclusion, oxidative stress biomarkers were negatively influenced by increased quantitative changes in stocking density.

Gürsul, Isil; Gueven, Alper; Grohmann, Anne; Knorr, Dietrich
Pulsed electric field (PEF), among numerous stresses, provides a large potential as an external stimulus to enhance secondary metabolite biosynthesis from plant cell cultures. PEF treatment was combined with the sub-culturing technique to increase phenylalanine ammonia lyase (PAL) activity, the key enzyme for secondary metabolite synthesis from tomato cell culture. In reference to the analysis, maximum accumulation of total phenolic (TP) compounds in the cells was determined as a function of stress reaction time (SRT). Also, PEF application increased PAL activity. PEF resulted in an increase in the porosity of the cell membrane, thus decreasing cell vitality. On the other hand, SRT decreased vitality, while increasing TP content. Sub-culturing enhanced the cell structure and improved the cell membrane permeability. PEF treatment potentially offers an alternative to other methods for increasing PAL activity in plant cell cultures. (C) 2016 Elsevier Ltd. All rights reserved.
