In this study, the effects of nanosilica (NS) additive on the water sensitivity of hot mix asphalt (HMA) pavements were investigated. For this, NS-modified asphalts were prepared by adding NS at rates of 1%, 3%, 5% and 7% by weight to the pure B 160/220 asphalt. In the study, first of all, the physical properties of pure and modified asphalts were determined by penetration, ductility and softening point experiments, and their viscosities were determined by rotational viscometer (RV) experiment. Then, the optimum asphalt content of the mix was determined according to the Marshall design method. Hot mix asphalt specimens were prepared by keeping this determined ratio constant for pure and modified asphalts. Prepared pure and NS added modified mixture specimens were subjected to Marshall stability, retained Marshall stability (RMS) and indirect tensile strength (ITS) tests. The physical test results showed that the hardness and machinability temperatures of the modified binders increased up to 5% NS. According to the mixture test results, it was determined that NS additive had a positive effect on the sensitivity of road pavements to water, since Marshall stability, RMS and indirect tensile strength ratio (ITSR) values showed significant increases at 5% NS.

In this study, in terms of their approach to the equivalent earthquake load method, a comparison of the Turkish building earthquake codes published in 2007 and 2018 was made. For the study a reinforced concrete residential building, which is thought to be designed for the Adiyaman provincial center and its other districts was selected. It is assumed that the residential building has three spanning in the x and y directions (in plane) and the structural system consists of columns-beams. The floor height of the building was taken as 3 m for each floor and the number of floor was chosen as six, considering the construction style of Adıyaman province. The first natural vibration period of the residential building was determined with the help of the Rayleigh ratio formula and the empirical approach. Then, according to both earthquake codes, the base shear forces were determined separately for different soil classes using the structural characteristics of the residential building. Firstly, each code was evaluated within itself, and then a comparison of the codes with each other was made.

Managing waste in big cities is a big problem. Wastes are dangerous in terms of causing environmental pollution and affecting human health. In particular, solid wastes such as glass and plastic do not dissolve in the soil for a long time and pollute the environment. By recycling such solid wastes, the surrounding waste can be reduced. Therefore, it is important to classify waste and to recycle the separated waste. In this study, a data set consisting of 22500 waste images was used. The data set contains color image data with a size of 227 x 227 pixels. The data used in the study are divided into two as organic and recyclable waste. This study proposes a deep learning-based system for classifying waste. With such a system, wastes can be classified and recycled. The data was trained with the ResNet 50 architecture and the CNN architecture created to classify waste, and accuracy rates were compared. The CNN architecture created to classify waste is more successful for this data set with an accuracy rate of 91.84%.
处理大城市的垃圾是一个大问题。废物在造成环境污染和影响人类健康方面是危险的。特别是玻璃、塑料等固体废弃物，不长期溶于土壤，污染环境。通过回收这些固体废物，可以减少周围的废物。因此，对垃圾进行分类和回收是很重要的。在本研究中，使用了由22500张垃圾图像组成的数据集。该数据集包含大小为227 x 227像素的彩色图像数据。研究中使用的数据分为有机废物和可回收废物两类。本研究提出一种基于深度学习的垃圾分类系统。有了这样一个系统，废物可以分类和回收。使用ResNet 50架构和CNN架构对数据进行训练，并比较准确率。对于该数据集，创建的用于垃圾分类的CNN架构更为成功，准确率为91.84%。

In this study, the three-point bending behavior of laminated composite plates reinforced with three-dimensional (3D) spacer fabric was experimentally investigated. Composite plate production was carried out using hand lay-up and vacuum infusion (VARI) method. Three-point bending test results of composite plates produced as a single layer were experimentally compared. Afterwards, composite plates with 2 and 3 layers were obtained by vacuum infusion method and load displacement graphs were obtained by subjecting them to three-point bending test. There was no significant difference between the load carrying capacities of the single-layer composite plates produced by hand lay-up and vacuum infusion method in the three-point bending test. According to the three-point bending test, the maximum load obtained 105 N in hand lay-up production is 8% greater than the vacuum infusion method. While the maximum load was 602 N in the plate produced in the 2-layer vacuum infusion method, it was obtained as 923 N in the 3-layer.

In this research, both environmentally friendly and economical composites have been produced by using biomass wastes in unsaturated polyester. The use of renewable biomass wastes as a filler in unsaturated polyester is reduced the carbon footprint of the composite obtained. A low-density and flexible structure could be achieved according to the intended use of polyester composites. While the density of the pure polyester polymer not reinforced with biomass is around 1206 kg/m 3 , the density of the 5 wt.% filler added composite decreases to 1167 kg/m 3 . Biomass waste ( Asphodelus aestivus L. ) reduces Shore D hardness of the polyester composite and turns it into a more flexible and easy-to-process material. It has been observed that the thermal conductivity coefficient of the biomass reinforced polyester composite shows a slight increase compared to the pure polyester composite. Besides, it has been determined that as the amount of biomass in the polyester composite increases, the activation energy decreases. The specific bond structure in the polyester polymer has been determined by Fourier transform infrared (FTIR) spectroscopy. Biomass waste is not making a chemical bond with polyester, it is only used as a filler. Also, the surface morphology of the polyester composite has been investigated with the help of scanning electron microscopy (SEM). The use of 3 wt.% Asphodelus aestivus L. biomass as a filler does not create a negative pore structure on the composite surface.
