The species of the Congridae family belonging to the Anguilliformes order are known as conger eel, and are morphologically similar to the eels which are among the species of the Anguillidae family. In both family species, the dorsal and anal fins are combined with the caudal fin. It is easily distinguished from eel species by the appearance of dorsal fin rays at a closer level to the head. There are 195 species belonging to 30 genus distributed in the world seas belonging to the Congridae family. A third genus of 3 species [Ariosoma balearicum (Delaroche, 1809), Gnathophis mystax (Delaroche, 1809) and Conger conger (Linnaeus, 1758)] shows the distribution of Turkish seas. While the first two species have distributed only Turkey's Aegean and Mediterranean seas, C. conger shows the distribution of all our seas. In this review, where morphological and biological characteristics of European conger are distributed in our country, all studies carried out both in our country and abroad are examined in detail and presented together. With this compilation study, especially biological information about species is missing in our country and attention has been made to contribute to the literature.

The aim of this study was to examine the drying kinetics of pears (Pyrus communis L.) with and without vacuum impregnation and under the different temperature by using tray dryer. Vacuum impregnation were applied to the the pears (15 mm thickness, 65 mm outer and 20 mm inner dimensions respectively) with the conditions of 50⁰ Brix impregnation solution concentration, 225 mbar vacuum pressure and 45 min vacuum time. Drying process was carried out at temperatures of 55, 65 and 75°C. Drying time of non-vacuum impregnated pears was determined 640, 500 and 340 min and vacuum impregnated pears was determined 700, 540 and 560 min respectively. Page, Exponential, Henderson and Pabis, Diffusion Approach were examined for testing the drying kinetics. Experimental values are in accordance with the expected values resulted Page and Difussion models of with and without vacuum impregnated pears. Effective diffusion coefficient (Deff) was varying 2.74×10-11 to 7.31×10-11 m2/s. m2/s with respect to the drying temperatures. The activation energy for the non-vacuum impregnated and vacuum impregnated pears was 32.93 kJ / mol and 24.25 kJ / mol, respectively.

Efficient use of water, one of the most critical life elements in the world, is becoming more and more important day by day. With the continuous increase in population and with climate change problems occur in terms of both consumption rate and usage patterns of water resources. It is becoming increasingly important to apply and research methods that can solve these problems all over the world. One of these solutions is the “Water Harvesting” method, which goes back many years. Water harvesting can be defined as the accumulation of runoff generated by precipitation to provide water for human, animal or crop use. While it is possible to see the use of the technique with roof and farm systems in micro-catchment dimension; wadi-bed and off-wadi (diversion) systems are used in macro-catchment dimension. In agricultural production, which uses a significant part of water resources, most of the rainwater falling into arid and semi-arid regions where production continues, goes away before could using efficiently by evaporation or flow. For this reason, the use of water resources becomes mandatory by using traditional irrigation methods in agricultural lands. With the water harvesting technique, after storing rain water, it can be held to be applied to crops. Hence the method since there will be no losses due to evaporation or flow, it will increase the total amount of irrigation water and reduce the pressure on water resources. Except for the protection of water resources, its role in preventing soil erosion is also seen as one of the main benefits of the method. In general, when the appropriate method is selected according to the appropriate geography, water harvesting has low inputs and is not difficult to apply. With a few exceptions, it does not require the use of pumps or energy input to deliver or deliver harvested water. In this study, information is given about the main elements, different usage areas and techniques of water harvesting.

The amount of secondary metabolites can be increased with different elicitor applications in vitro. It has been determined that zinc sulphate significantly increases the amount of capsaicin in the cell culture of red hot pepper. It is important to determine how the metal applied as elicitor will have an effect on plant metabolism. In the study, it was aimed to determine the effects of zinc sulphate (ZnSO4) applied to the cell suspension cultures of pepper seeds at different concentrations (0.1 M, 0.2 M, 0.4 M) and for periods (24, 48, 72 hours) on the total protein and phenolic substance amounts, and superoxide dismutase-peroxidase enzyme activities of pepper calluses. It was observed that the amount of protein increased, superoxide dismutase and peroxidase enzyme activities decreased, and the total amount of phenolic substance increased especially in 72 hours of treatment where zinc was applied as elicitor. These results show that ZnSO4 can be used as an abiotic elicitor in plant cell culture media.

With the increase in the population in the world and in our country, the energy requirement related to consumer demands is constantly increasing. In our country, although wind, sun, etc. energy sources are used in energy production, fuels of fossil origin (coal, natural gas, oil etc.) are used more in energy production. Renewable energy sources, which are alternative due to the decrease in fossil fuel reserves, negative environmental effects and inability to meet the energy needs in the future, come to the fore. In this study, Turkey Statistical Institute (TUIK) according to the 2015-2019 year data, Sakarya at the central and districts in cultivation areas for cultivated of using the amounts of maize and wheat product (da) average waste, dry matter, and volatile dry matter, methane and energy their potential has been determined. As a result of the calculations, it has been determined that the maize sap waste amount has the highest 25695.68 tons of waste and 201197.15 MJ energy potential in Adapazarı district in 2017. Among the wheat stalk wastes, in 2017, Geyve district had the highest 269.95 tons of waste and 2113.72 MJ energy respectively.

In the food industry, using of new preservation and processing technologies, which may be an alternative to traditional methods, is becoming increasingly important. These novel and particularly non-thermal techniques have very important advantages such as enhancing food safety, reducing quality losses, and increasing production efficiency. One of these new technologies, Pulsed electric field (PEF) technique, stands out as a novel method that has been emphasized in recent years. It is used for different purposes in both liquid and solid foods, also various studies are carried out for the optimization. On the other hand, recently, there are several studies using PEF technique in meats and seafoods for the preservation purposes, as well as other positive effects (improving the functional properties of the product, accelerating processes such as drying, curing and freezing). In this regard, detailed information about the purposes for which PEF technique can be used in meats and seafoods has been tried to be given in this comprehensive review study.

In this study, the average drying times of the Frigos, Bilensoy, Nimet and Prosementi alfalfa varieties were determined by drying in a convective dryer (50, 60 and 70°C) and in the open (sun). In addition, the most suitable thin layer drying models were determined, which are important in controlling the drying processes and developing new product-specific dryers. In drying processes, the moisture content of the product was dried up to 10% compared to the wet base. The first moisture contents of the specified varieties according to the wet base are respectively; 76.20, 75.88, 76.13 and 75.07%. In drying processes, it was determined that drying method and temperatures changed average drying times. The longest drying times were determined in the Frigos variety, which was laid in the sun and dried. When the Frigos variety was dried in the oven at 50, 60 and 70°C, the average drying times were determined as 11, 10 and 6 hours. Time-dependent moisture ratios were determined, processed in thin layer drying models and the mathematical model that best predicts drying curves was determined. While creating curves, Page, Midilli, Yağcıoğlu models were used. While acceptable reliability values were found as in all models, among the models, the highest stability value (R2) was found by Midilli was found in equality.

This study was carried out between 2017 and 2018 to determine physical and chemical influences of two drying methods (drying on wooden fruit drying trays and drying cloths), two harvesting periods (commercial / physiological maturity and late harvest), and two harvesting methods (harvesting by hand and shaking) on dried fruit samples of Hacıhaliloğlu and Kabaaşı cultivars. Titrable acidity, browning level, total phenolic content, antioxidant activity (ABTS), color (L*, a*, b*), pH, humidity and water activity (aw) parameters of dried fruit samples were examined. Results indicated that different harvesting periods, methods and drying methods significantly affected almost all fruit quality parameters. L value was higher in apricots dried on trays than dried on the cloths. L* values of dried apricots ranged from 27,13 to 54,74. Similarly, moisture content and water activity values were also found to be lower in apricots dried on wooden fruit drying trays than dried on clothes. When chemical parameters were examined, it was observed that phenolic compounds and total antioxidant contents decreased with fruit ripening. The effect of the applications on drying efficiency was not determined as significant, on the contrary, the individual weights of the dried apricots harvested at the late period were found significantly higher and the number of dried apricots per kilogram was lower. As a result of the study, it was concluded that in sun-dried apricot production, harvesting at late period and the drying on trays positively affected various quality parameters.

After realizing that multi-storey buildings are contrary to human nature, the importance of natural landscape and green areas around it has been noticed. For this reason, people want to see how their environment will be in the design phase and the importance of project presentations is increasing day by day. Information technologies for spatial thinking, imagination and modelling have gradually started to be included in landscape design processes. The concept of virtual reality, augmented reality and immersive virtual reality are becoming more and more involved in our lives due to reasons such as the size of the devices getting smaller and their prices being relatively accessible to everyone. As an alternative to traditional presentation techniques and two-dimensional presentation techniques on the computer, making presentations in a virtual reality environment can be a stronger factor in people’s perception of the environment. In the study visual sets in basic, intermediate and advanced level of detail for the same landscape design and project site have been created. Each set consists of hand-drawn perspective image, computer aided perspective image, stereoscopic 360-degree VR image and an augmented reality model. In order to evaluate these visual sets, interviews were made with 10 landscape architects who are experts in the subject. As a result of the study, criteria’s for landscape presentations has been discussed and the advantages and disadvantages of landscape design presentations that will be created using virtual and augmented reality have been evaluated.
