Background: Breast cancer is the second leading cause of death in females worldwide. Mammograms are useful in early cancer diagnosis as well when the patient can sense symptoms or they become observable. Inspection of mammograms in search of breast tumors is a difficult task that radiologists must carry out frequently. Objective: This paper provides a summary of possible strategies used in automated systems for a Read More

Aims: Finding a simple, energy-saving and low-cost synthesis method to process gallium oxide nanowires by CVD for solar-blind detector. Background: Due to a bandgap of 4.5 ~ 4.9 eV and a high breakdown field strength of 8 MV/cm, gallium oxide (Ga2O3) has great application prospects in solar blind ultraviolet detection and highpower devices. Notably, Ga2O3 NWs are currently the key research objects of solar Read More

The shoot apical meristem of seed plants gives rise to the above-ground parts of the plants during development, including leaves, stems, and lateral meristems. Among them, two types of meristems, axillary meristem and vascular cambium, support the main lateral growth. In this review, we will discuss the regulatory network of lateral growth, focusing on recent progress made mainly in Arabidopsis thaliana, tomato and Read More

Background: The primary sources of nitrate contamination in groundwater resources are excessive fertilizer use and unregulated land discharges of treated wastewater. Due to its harmful nature to human health and its contribution to eutrophication, the removal of nitrate from water has been of great interest in the last decades. Various techniques, such as adsorption, ion exchange, catalytic and biological denitrification, Read More

Background: Spatial variability of stable isotope ratios in water from River Ganges is preserved in aragonite or calcite present in otoliths and formed at equilibrium with ambient water. This technique is used for a set of long-whiskered catfish aragonite otoliths from four different locations along the course of the River Ganges. Methods: Acid digestion of otolith and the analysis of δ13C and δ18O in these carbonates using an isoto Read More

Background: The pellet shaft furnace is widely used to roast pellets, which is essential for the blast furnace burden structure; however, the study on the roasting process in the pellet shaft furnace is very critical for obtaining high-quality pellets. Objective: A theoretical model of the pellet roasting process in the pellet furnace (8m2) has been developed on the basis of reaction engineering. The present study aims at investigating th Read More

Background: This paper reports a versatile bentonite clay-mediated growth method for selectively synthesizing zero-dimensional α-Fe2O3 nanoparticles and one-dimensional α-FeFe2O3 nanorods. Methods: In such a growth process without any other surfactant or additive, the bentonite clay is not only used as the supporter, but also as a shape mediator for α-Fe2O3 nanocrystals. The products were characterized by X-ray Read More
