The kinetics of crystallization of different crystalline phases of Fe73.5Au1Nb3Si13.5B9 has been studied by differential thermal analysis (DTA). DTA diagrams of amorphous ribbons were taken in nitrogen atmosphere with continuous heating rate of 10 -50°C/min in step of 10°C. The primary exothermic peaks temperature for α-Fe (Si) was found 5680C and the secondary exothermic peak temperature for Fe2B phase was found 6810C at the same heating rate 200C/min. Thermal analysis experiment and from the obtained data the activation energy is found 2.50eV. For primary crystallization product, α-Fe(si) phase of the ribbon and nanocrystalline state was evaluated by XRD. The alloy has been annealed in a controlled way in the temperature range of 4500 C to 8000C for 30 minutes. By XRD experiment crystallization onset temperature for α-Fe(si) phase was found around 6500C.The lattice parameter, the Si content in bcc nanograins and the grain size of bcc grains can easily be calculated from the fundamental peaks of (110) reflection. In the optimized annealing condition the grain size has been obtained in the range 13-25 nm. The lattice parameter and Si at % shows an inverse relationship indicating that silicon diffuses out of α-Fe(si) grain for which the size α-Fe(si) lattice is regained.. The curie temperature was found 667OK.

This project focuses on the comparison of Orthometric heights obtained using Total Station and Differential Global Positioning System (DGPS) with precise Levels. The Surveys executed were on existing second-order controls established along Durbar – Akinnmoorin road, Oyo, Oyo State. The obtained Easting, Northing, and height (Ellipsoidal) coordinates of the points were from the observation of the Trimble Dual Frequency GPS receivers. Trigonometric heighting was by the Leica TS02 Total station while the reduced levels of those points were by the Leica Sprinter Digital level in a geodetic-mode. The transformation of the Ellipsoidal heights obtained through DGPs to orthometric heights is by selecting the EGM 96 option in the processing software. Comparison is then made between the heights obtained using the total station and the differential GPS using the precise level as the reference height.........

The effects of climate change have a significant impact on the built environment. One method of determining climate vulnerability could be the framework recommended by the IPCC, the main elements of which are exposure, sensitivity and adaptability. The aim of the present study is to find factors that can be derived from geometric data and simple visual inspection and are suitable for determining the sensitivity of multi-apartment residential buildings. Given that almost one-eighth of the Hungarian housing stock was built with prefabricated technology, the study focuses on these buildings. The data used for the analysis come from the National Adaptation GIS System, from OpenStreetMap database, and visual inspections. The methods of the research were literature review, calculations in MS Excel and data visualization in GIS software............

Coral reef ecosystems are a wealth of marine resources that have an important role in supporting the lives of various aquatic organisms. This is because reef fish go through a phase of life partially or completely on coral reefs, so that coral reefs become a place to live, a place to look for food, a shelter and a place to breed. The types of data collected for the purposes of this study are primary data and secondary data. Primary data collection by observing the field using the Underwater Fish Visual Cencus (UVC) method to find out the types of fish associated with coral reefs. The diversity index of reef fish ranges from 2.96% - 3.97%. This value includes the category of high diversity (H '> 3) because there is a good balance of ecosystems in Fragrant Fragmentation, uniformity index (E) of reef fish ranging from 0.55 to 0.97%, uniformity of species of reef fish at the base of Fragrant Scales -wangi as a whole is considered to be a stable type of fish species...........

Due to the increasing production and use of engineered nanoparticles, it is expected that their concentration in various environmental compartments will grow up. This fact is related to the increasing demand of their reliable quantification in environmental matrices. However, the reliable quantification of nanoparticles in complex matrices is not an easy task. It is mainly due to extremely low concentrations of nanoparticles and complicated coexisting matrix. For this purpose, the adaptation of existing techniques and methods, or the development of new ones is necessary. Among engineered nanoparticles, silver nanoparticles (AgNPs) belong to the group of the most frequently used nanomaterials. This review demonstrates that a combination of well-established extraction procedures (namely liquid-liquid extraction, cloud point extraction, solid phase extraction, and magnetic solid phase extraction) and commonly available spectrometric methods can be considered as promising alternative for separation/preconcentration and quantification of AgNPs in various types of environmental waters and some antibacterial products.

The apolipoprotein A1 (APOA1) is a component of high-density lipoprotein (HDL) in plasma, playing aspecific role in lipid metabolism. Defects in this protein have been associated with several diseases, including familial HDL deficiency, familial visceral amyloidosis and increase risk of cardiovascular disorders. Among the possible causes of these defects are single nucleotide alterations within the coding region of the APOA1 gene, which could affect protein function. This study aims to analyze the possible impact of 15 variants of unknown significance identified within the APOA1 gene. A total of 12 in silico SNP impact prediction tools were used to evaluate the impact of these alterations. The predictions suggested that four of these alterations(Pro123Ser, Arg140Leu, Ser191Asn and Ser191Arg)could result in protein disfunction.
