    Investigation of Usability of Boron Doped Sheep Wool as Insulation Material and Comparison With Existing Insulation Materials
    (Elsevier Sci Ltd, 2022) Altın, Mustafa; Yıldırım, Giray Şamil
    The limited energy resources in the world require maximum attention in energy saving and energy use. It has always been important to conserve energy by making thermal insulation in buildings which are one of the places where energy is used the most, and subsequently reducing environmental pollution as a result. The importance of existing thermal insulation materials in maintaining heat is already known. However, the damage they cause to the environment in their production is great, therefore insomuch that the manufacture and use of some insulation materials are prohibited. As a result, it is known that studies have been carried out to produce alternative thermal insulation materials. In this study, as a thermal insulation material, the usability of sheep wool which is an environmentally friendly, economical, and natural fiber, has been researched. A new insulation board was produced by adding boron to sheep wool, and this new insulation board was compared with rock wool and expanded polystyrene (EPS), which are widely used today. To carry out the experimental studies, an experiment building with full size and 3 rooms had been built. First, the building was completely covered with rock wool and the effect of the facades on the temperature and moisture in the environment was observed. Afterwards, as one room was covered with EPS and the other room was covered by the boron doped sheep wool insulation material, the insulation materials were compared wtih one another. In the experimental studies that was carried out, while rock wool gave the best results in ambient and surface temperature tests, EPS provided the best insulation in the moisture test. In the sound test, while rock wool and EPS absorbed the sound at very close decibel levels, the boron-doped sheep wool insulation material provided a higher level of sound insulation. In the experimental studies that was carried out, it has been determined that the boron-doped sheep wool insulation material has serious competition with both rock wool and EPS even with the first production of 10 mm.

    Land Valuation With Best Worst Method in Land Consolidation Projects
    (Elsevier Sci Ltd, 2022) Ertunç, Ela; Uyan, Mevlüt
    Land Consolidation is the regulations made to increase agricultural productivity. In these projects, improperly shaped parcels are optimally rearranged in the land allocation process and reallocated to predetermined blocks. The amount of the land to be reallocated depends on the value of parcels. Because, after land consolidation in the project area, it is necessary to determine the value of existing parcels based on certain factors so that the landowner will be provided with the land of equal value to its previous land. In land consolidation projects, determining the value of the land, developing and recommending principles acceptable to the landowner, and the overall duration of the project are of critical importance for the quality and success of the project. In other words, the key to the positive evaluation of the whole project is to determine the value of the land transparently and without causing injustice among landowners. The methods used in land valuation in many countries fall behind the existing techniques and technologies. Therefore, a new approach based on scientific methods is needed for land valuation. To this end, a new model based on multi-criteria calculations, which is compatible with today's technologies and eliminates weaknesses in the existing land valuation methods, has been developed in this study. In the model, the most important factors affecting the land value in land consolidation projects were determined, and the value of parcels in the consolidation area was determined by weighting these factors using the Best Worst Method (BWM). The BWM is a new Multi-Criteria Decision Making (MCDM) method in the literature and has been used for the first time in this field. In the study, three different scenario models were created to investigate how the factor influencing land value are allocated during the land valuation. The generated land value maps were examined from different aspects, and the results were revealed. In conclusion, the proposed method performed an analytical, objective, and transparent land valuation since it objectively evaluates the factors used in land valuation by a scientific method.
