SUGAR BEET QUALITY COMPONENTS <p><em>This is the first in a series of papers describing the effects of potassium applications on drought stress in sugar beet. Drought stress is the stress to which there is the most exposure in agricultural areas. In this research, the effect of potassium applications under drought stress on some quality parameters of sugar beet, which is a strategic plant, was investigated. In the experiment, irrigation levels were kept at 33%, 66% and 100% of field capacity. Different doses (10-20-40-80 mg kg-1) of potassium were applied to the plants. The plants were grown in the growth chamber under controlled conditions (day/night 16/8 hours, 25/15 0C, 60-70% humidity). A comparison of the plants irrigated at the level of 100% of the field capacity and stressed plants showed that the root sugar content decreased by 53.18% and 65.1%, and shoot sugar content by 20.8% and 17.8% respectively at 66% and 33% irrigation levels. Root white sugar content (58.61 mg g-1) was obtained at the dose of 10 mg kg-1 potassium level, while the lowest (32.61 mg g-1) was obtained at the dose of 80 mg kg-1 potassium level. Shoot protein content has increased significantly with an increasing level of potassium under drought (33% and 66%) condition. The root α-amino nitrogen content decreased under drought stress with increasing potassium concentrations while it increased in non-stressed plants. According to the results obtained from the experiment, the potassium applied to the plants under drought stress led to the increase of the root sugar, root white sugar content and shoot protein content the reduction of root α-amino nitrogen content. Therefore, it can be said that potassium may play a critical role in reducing the negative effect of drought stress in sugar beet.</em></p> Gizem AKSU, Hamit ALTAY Copyright (c) 2020 Rating Academy Ar-Ge Yazılım Yayıncılık Eğitim Danışmanlık ve Organizasyon Ticaret Ltd.

In this research, extracts of Z. officinale rhizomes were prepared with different solvents (ethanol, methanol, distilled water, DMSO). Zingiber rhizome extracts were sprayed on the leaves of rio grande and marmande varieties of 10-12 weeks old Solanum lycopersicum plantlets. Total protein amount and peroxidase activity were examined by spectrophotometrically 24 and 48 hours after the application. According to the results, it was determined that the maximum increase in the total protein amount compared with the control group was 31.31% and 25.53% in marmande and rio grande varieties in ginger rhizome extract prepared with methanol, respectively. The increase in peroxidase activity was determined as 144.14% and 124.85% in marmande and rio grande varieties in ginger rhizome extract prepared with ethanol, respectively. As a result of our research, it was determined that rhizome extracts of Z. officinale can be used as natural plant activator.</em></p> Zeynep ÖZCEYLAN, Cüneyt AKI Copyright (c) 2020 Rating Academy Ar-Ge Yazılım Yayıncılık Eğitim Danışmanlık ve Organizasyon Ticaret Ltd.

In practice, sand grains are passed through a set of known mesh sizes by mechanical vibration and for a fixed period then the weight of sediments retained on each sieve are measured and converted into the percentage of the total sediment (PTS). This procedure is applied to all core samples and the resulted PTS data are used for characterizing grain size distribution using one of the sieve analysis procedures. The core-by-core method, for example, is one of the conventional methods that PTS data from each core sample are used individually to estimate mean, sorting and other dependent parameters to grain size distribution. In this method, applying a robust statistical method to integrate all PTS data and picking out the most probable size from all cores is a challenge. </em></p> <p><em>A new approach is introduced in this paper as sieve-by-sieve method, whereby the grain weight distribution data are classified based on mesh sizes (as bins) and the most probable size in each class is picked out among all cores directly and without any manipulation or averaging. </em></p> <p><em>In this paper, the performance of both methods are compared in a homogeneous media and a heterogeneous media. In a homogeneous media, both methods provide comparable results. However, in a heterogeneous media, the core-by-core provides too many distributions which sometimes are not conclusive but the sieve-by-sieve provides the profiles of minimum and maximum weight of retained grains, which facilitates picking out the most probable size among all cores.</em></p> Kourosh KHADIVI, Shahab HEJRI, Shapour VOSOUGHI Copyright (c) 2020 Rating Academy Ar-Ge Yazılım Yayıncılık Eğitim Danışmanlık ve Organizasyon Ticaret Ltd.

In this study, it was used to optimize the resistance value of train sets.</em></p> <p><em>There are many types of resistance in train sets and the train can't start moving until the traction motors overcome the resistances. Run resistance, ramp resistance, and curve resistance are the resistances that the train must overcome at a constant speed. However, it is known that the acceleration of high-speed trains is very high and the resistance that the train sets must overcome for the change in speeds is acceleration resistance.</em></p> <p><em>This study aimed to calculate the acceleration, time, curve, ramp and distance, under certain constraints, for the total resistance value of YHT 65000 train by using the Particle Swarm Method as to obtain the minimum and maximum. Although, the results showed that the Particle Swarm Method returned very successful results for the minimum resistance, the same cannot be said for the maximum resistance.</em></p> Mi̇ne SERTSÖZ, Mehmet FİDAN Copyright (c) 2020 Rating Academy Ar-Ge Yazılım Yayıncılık Eğitim Danışmanlık ve Organizasyon Ticaret Ltd.

Over the last decades, evolutionary algorithms have been largely used in solving optimization problems in various fields of science. The aim of this study is to evaluate the performance of a constrained version of the Non-dominated Sorting Genetic Algorithm 2 (NSGA 2), a multi-objective evolutionary optimization algorithm, written in MATLAB. The developed NSGA 2 is compared, in terms of convergence and diversity of the obtained solutions, to a number of popular constrained multi-objective evolutionary algorithms from the literature. Widely used four benchmark problems (including CONSTR, OSY, SRN, and TNK problems) with varying difficulty and type of constraints are reviewed and used. The NSGA 2 obtained the lowest values of inverse generational distance (IGD) values for almost all the problems. These results show that the developed constrained NSGA 2 is an effective technique and is competitive to the other optimization methods in the literature.</em></p> Youssef ALIOUI, Reşat ACAR Copyright (c) 2020 Rating Academy Ar-Ge Yazılım Yayıncılık Eğitim Danışmanlık ve Organizasyon Ticaret Ltd.

Loss on inginitions, fired bending strengths, dry strength, fired shrinkages, water absorbtion and colorimeter degrees were measured. Microstructure was determined by scanning electron microscope (SEM), energy dispersive x-ray spectrometer (Edx) and x-ray diffractometer (XRD) measurements. After sintering, it was determined that 2 wt.% fly ash can be used in granite body. In sintered body, according to XRD phase analysis, amount of free quartz and mullite decreased and albite formation was observed. While the fired strength value is 399 kg/cm2 in standard body, it is 315 kg/cm2 in 2 wt.% fly ash added body. In the experiment with 2 wt.% ash additive, according to SEM images, the number and volume of large pores increased while small pores decreased. The ability of pressing of the sample with 10wt.% ash additive was negatively affected due to the excess amount of fine ash and so occure lamination and bloating.</em></p> Savaş ELMAS Copyright (c) 2020 Rating Academy Ar-Ge Yazılım Yayıncılık Eğitim Danışmanlık ve Organizasyon Ticaret Ltd.
