Hysteresis and Compensation Behaviors of Mixed Spin-1 and Spin-2 Hexagonal Ising Nanowire System

By utilizing the framework of the effective field theory with correlation, hysteresis and compensation behaviors of mixed spin-1 and spin-2 hexagonal Ising nanowire system is investigated in detail. The effects of Hamiltonian parameters on hysteresis behaviors are discussed, in detail. The compensation behavior of the system is also studied and according to values of Hamiltonian parameters, the Q-, S-, R-, and N-type compensation behaviors is obtained in the system. Finally, the obtaining results are compared with some experimental and theoretical results and found in a qualitatively good agreement.     

Flower pollination algorithm: A novel approach for multiobjective optimization

Multiobjective design optimization problems require multiobjective optimization techniques to solve, and it is often very challenging to obtain high-quality Pareto fronts accurately. In this article, the recently developed flower pollination algorithm (FPA) is extended to solve multiobjective optimization problems. The proposed method is used to solve a set of multiobjective test functions and two bi-objective design benchmarks, and a comparison of the proposed algorithm with other algorithms has been made, which shows that the FPA is efficient with a good convergence rate. Finally, the importance for further parametric studies and theoretical analysis is highlighted and discussed.     

Determination of energy balance of sugar beet production in Turkey: a case study of Kırklareli Province

This study aimed to make an energy analysis of sugar beet production in K?rklareli Province of Turkey during production season in 2012–2013. In order to determine energy input-output of sugar beet, the surveys were performed in 48 sugar beet farms, selected by using Neyman method, located in K?rklareli Province. The data were collected by face-to-face questionnaires and observations. The energy input and output were calculated as 34,201.75 and as 285,600 MJ ha^?1, respectively, in sugar beet production. Energy inputs consist of 41.97 % chemical fertilizer’s energy, 21.16 % diesel fuel energy, 11.97 % irrigation, 11.96 % electricity energy, 6.47 % human labour energy, 5.53 % machinery energy, 0.61 % seed energy and 0.33 % chemical energy. Energy usage efficiency, energy productivity, specific energy and net energy in sugar beet production were calculated as 8.35, 1.98 kg MJ^?1, 0.50 MJ kg^?1 and 251,398.25 MJ ha^?1, respectively.     

The relationship between neutrophil‐to‐lymphocyte ratio and vascular calcification in end‐stage renal disease patients

Chronic inflammation was found to be correlated with coronary (CAC) and thoracic peri‐aortic calcification (TAC) in end‐stage renal disease (ESRD) patients. Neutrophil‐to‐lymphocyte ratio (NLR) was introduced as a potential marker to determine inflammation in cardiac and noncardiac disorders. Data regarding NLR and its association with TAC and CAC are lacking. We aimed to determine the relationship between NLR and vascular calcification in ESRD patients. This was a cross‐sectional study involving 56 ESRD patients (22 females, 34 males; mean age, 49.9 ± 14.2 years) receiving peritoneal dialysis or hemodialysis for ≥6 months in the Dialysis Unit of Necmettin Erbakan University. TAC and CAC scores were measured by using an electrocardiogram‐gated 64‐multidetector computed tomography. NLR was calculated as the ratio of the neutrophils and lymphocytes. There was a statistically significant correlation between NLR, TACS and CACS in ESRD patients (r = 0.43, P = 0.001 and r = 0.30, P = 0.02, respectively). The stepwise linear regression analysis revealed that age, as well as NLR were independent predictors of TACS. However, increased age was the only independent predictor of CACS according to linear regression analysis. Simple calculation of NLR can predict vascular calcification in ESRD patients.
