Abstract In this study, the Polyamide-12 (PA-12) powdered material in the Selective Laser Sintering (SLS) process has been incorporated as the filler in the composite material to enhance its properties. The PA-12 powder has been made into a form of filament and is primarily used in the Fused Deposition Modelling (FDM) process. The PA-12 has been used with epoxy resin and glass fiber with different proportions. The characterization of materials, including the validation of the presence of PA-12 filler with epoxy, has been evidenced using Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), and Thermogravimetric More >

Abstract Severe earthquakes in the world and in Turkey can cause great loss of life and property, environmental problems and health problems. In addition to the loss of life and property, earthquakes are closely related to ecosystems, air, water, and soil pollution. Particularly in post-earthquake debris removal, very large amounts of particulate matter are released and may have negative effects on the health of the local population. This study aimed to detect two types of particle matter pollution during debris removal in 25 different locations in Adiyaman City using a CEM DT 9880 particle matter measuring… More >

Abstract Various biological constraints including erratic and asynchronous flowering between male and female plants hinder successful hybrid development and genetic gains in greater yam breeding programs. Therefore, pollen storage has gained much attention to facilitate artificial pollinations and increase the genetic gains. This 4-year study aimed at developing a practical long-term pollen storage technique for the successful development of yam hybrids. Fresh pollens were collected from two Dioscorea alata males, then lyophilized (two lyophilization treatments were applied), followed by storage at room temperature (24°C–25°C) for 12 months. Moreover, the lyophilized and stored pollens were tested for viability… More >

Abstract Drilling technologies based on oil-based drilling fluids and strong inhibitory saltwater fluids are affected by drawbacks such as downhole accidents where sticking and wellbore instabilities occur. Existing polyamine drilling fluids also exhibit problems such as easy decomposition and poor inhibition performances. In order to mitigate these issues, additives can be used, such as polyamine inhibitors and the synthesis of nanometer filtrate reducers. Tests conducted in the frame of this study with a polyamine drilling fluid and such additives show that this fluid has the same inhibitory, plugging, lubricating, and wellbore-stability performances as oil-based drilling fluids.

Abstract One of the elementary operations in computing systems is multiplication. Therefore, high-speed and low-power multipliers design is mandatory for efficient computing systems. In designing low-energy dissipation circuits, reversible logic is more efficient than irreversible logic circuits but at the cost of higher complexity. This paper introduces an efficient signed/unsigned 4 × 4 reversible Vedic multiplier with minimum quantum cost. The Vedic multiplier is considered fast as it generates all partial product and their sum in one step. This paper proposes two reversible Vedic multipliers with optimized quantum cost and garbage output. First, the unsigned Vedic… More >

Abstract Polyamines play an important regulatory role during plant growth and development and adversity stress, and polyamine oxidase (PAO) is involved in polyamine catabolism. In this study, an up-regulated polyamine oxidase gene GmPAO1 was obtained by transcriptome sequencing analysis and screening at soybean seedling stages. Also, its expression pattern and function were analyzed. The identification results of transgenic GmPAO1 soybean positive lines showed that the relative expression level of GmPAO1 in the overexpressed lines was increased under salt stress. With increasing stress concentration, the seed germination rate decreased. However, the seed germination rate of the overexpressed lines was… More >

Abstract Pea is a seed legume. It is rich in cellulose fibre and protein. It is also a significant source of minerals and vitamins. In this paper, we set out to better characterize the physiological responses of Pisum sativum L. to the combined effects of NaCl, 100 mM and gibberellins (GA3). Our analysis revealed that NaCl caused a decrease in growth resulting in a reduction in root elongation, distribution and density, leaf number and leaf area, and a decrease in dry matter of roots and shoots. However, the contribution of GA3 in the salty environment induced an… More >

Abstract One of the major problems faced in managing biomass waste to higher quality products is choosing the right technology. Wastes are used as an alternative fuel, with increase in the calorific value. Hydrothermal carbonization (HTC) is a biomass conversion technology, used to obtain solid fuel. This study aims to utilize of Calophyllum inophyllum as an alternative solid fuel through HTC. The calorific value and proximate of the hydrochar will be determined and analyzed to find out its quality. The experiments were carried out at temperature variations of 160°C, 190°C, and 220°C and holding times of 30… More >

Abstract Manganese (Mn) is one of the essential microelements in all organisms. However, high level of Mn is deleterious to plants. In this study, the effects of exogenous manganese application on mineral element, polyamine (PA) and antioxidant accumulation, as well as polyamine metabolic and antioxidant enzyme activities, were investigated in Malus robusta Rehd., a widely grown apple rootstock. High level of Mn treatments decreased endogenous Mg, Na, K and Ca contents, but increased Zn content, in a Mn-concentration-dependent manner. Polyamine metabolic assays revealed that, except the content of perchloric acid insoluble bound (PIS-bound) spermine, which increased significantly,… More >
