Abstract
Laser-induced breakdown spectroscopy (LIBS) to detect the light elements such as lithium (Li) and boron (B) and heavy elements such as copper (Cu) and lead (Pb) in raw fish samples is reported in this work. This is made possible by understanding that the soft target absorbs recoil energy and as a result, the ablated atoms gushing from the soft target do not acquire sufficient speed to form a shock wave. In order to overcome this problem, we set a subtarget on the back of the soft target so as to produce the repulsion force by which the gushing speed of the ablated atoms is increased, yielding a sufficiently high plasma temperature or sufficiently large thermal energy needed for the excitation of the ablated atoms. Excellent spectral qualities of various soft samples such as margarine, butter, peanut butter, strawberry jam, raw tuna, raw gindara, and raw salmon are presented. Furthermore, a linear calibration curve with a zero intercept is also obtained for Li, Cu, and Pb. The detection limit of Li, Cu, and Pb is

Metrics & More Article RecommendationsABSTRACT: A three-dimensional trial bed is established for a staged combustion boiler, and a modeling method based on similarity theory is proposed. The aerodynamicfield of the 35 t/
h layer combustioncomposite combustion chamberin the stoker boiler with staged combustion was evaluated. Further, a three-dimensional calculation model based on computational fluid dynamics (CFD) was used to simulate the aerodynamic field of the reformed boiler under normal operation, which facilitated convenience in the boiler design.
Hot-wire anemometer and other instruments were used for the characteristic test of damper, a velocityfield test in the furnace, wall wind test, temperature balance test at the outlet of the furnace, etc., and the law of motion for theflowfield in the furnace was obtained. By analyzing the structure of staged combustion, the emission of nitrogen oxides and the combustion stability of a novel layer-fired boiler were studied. The calculated results are in excellent agreement with the experimental data. The results revealed that the combustion efficiency of the boiler and the reduction of nitrogen oxides were significantly improved by the staged
combustion technology. There was no erosion on the water wall, and theflow velocity at the outlet of the furnace was uniform. This modeling method exhibits good adaptability to the combustion of stratified combustion boilers and is potentially useful for optimizing furnaces in a variety of applications.
1. INTRODUCTION
China is one of the biggest consumers of coal resources in the world. In 2017, the total energy consumption was 4.49 billion tons of standard coal, with coal accounting for the largest part of the energy structure.1 The furnace is essential equipment for transforming chemical energy into heat. The quality of combustion in the furnace not only influences the safety and economic efficiency of the unit but also determines the environmental impact of combustion-induced pollutants.2The quality of combustion is primarily governed by the distribution pattern of the airflowfield in the furnace.3In several industrial furnaces, the proportion of stoker furnace is about 65%.4During the operation of a conventional stoker furnace grate, coal particles move and combust simultaneously on the furnace grate.5Coal particles pass throughfire on one side and distinct regions are evident on the fuel layer along the direction of the length of the furnace of the furnace grate.6 The combustion efficiency is relatively low in view of the combustion reaction speed, space−time efficiency of combustion, and quality of combustion.7Consequently, the thermal efficiency of industrial furnaces on the stoker furnace grate is not high and ranges between 60 and 80%.8
The poor quality of combustion in a bed-fired boiler leads to poor coal adaptability, low combustion efficiency, and insufficient output in the boiler.9−11To this end, Wang and
Qu12 proposed a novel method to improve the combustion efficiency of chain boilers called the staged combustion method.
The main characteristic of this method is that the swirl burners are arranged opposite to each other on both sides of the furnace wall, and two different combustion modes are realized in the furnace, which are laminar combustion and suspension combustion. The two combustion modes complement and promote each other, thus providing an efficient combustion mode for laminar combustion boilers. Zhao and Huang13 deduced the material balance andflue gas heat balance equations for a staged combustion chain boiler, thereby establishing the basic equation for furnace heat transfer. Du and Shen14 retrofitted a 2 t/h laminated-fired boiler by staged combustion.
Because the aerodynamic field test of the system was not performed in the previous stage, the water wall was severely scoured after the coupled combustion of room-fired pulverized coal and large granular coal, and theflue gas temperature at the outlet of the furnace was unstable, which reduced the reliability

sı Supporting InformationABSTRACT: Nowadays, crop protection is a major concern and how to proceed is a delicate point of contention. New products must be safe and ecofriendly in accordance with the actual legislation. In this context, we present a quantitative structure−activity relationship strategy based on molecular topology as a tool for generating natural products as potential fungicides following a mechanism of action based on the synthesis of chitin inhibition (chitinase inhibition). Two discriminant equations using statistical linear discriminant analysis were used to identify three potential candidates (1-methylxanthine, hematommic acid, and antheraxanthin). The equations showed accuracy and specificity levels above 80%, minimizing the risk of selecting false active compounds.

INTRODUCTIONNowadays fungi cause crop losses worldwide, with fungal diseases having a significant economic impact on plant yield and quality; thus, managing such diseases is an essential component of production for most crops.1,2The identification of molecules targeting enzymes and/or biochemical processes almost exclusive in fungi is a useful approach for agrochemical companies when fighting resistant infestations. Fungal cell walls are primarily composed of polysaccharides, namely chitin, glucans, mannans, and glycoproteins. Chitin is one of the main components, and it is not present in plant cells.3Basically, it is a eukaryotic extracellular amino sugar biopolymer, massively produced by most fungal systems and by invertebrates, notably arthropods. For its importance in fungi life cycle, chitin has been considered as a selective target for pesticide action.4It is synthesized by chitin synthase and cleaved by chitinase which degrades or remodels the cell wall. This way, it is capable to maintain cell wall plasticity during growth. Fungal chitinases are crucial for cell division and replication and also for cell wall remodeling. In addition, they play an important role in cell nutrition, morphogenesis, and development processes; so, the importance as potential targets is clear.5,6 Chitin synthesis inhibitors were considered new since 1977.7Over the past few decades, a variety of chitinase inhibitors were identified and characterized. The majority of potent chitinase inhibitors are naturally derived products such as pseudotrisaccharide allosamidin and cyclic peptides such as argifin, psammaplin, and argadin. Chemically, many reported chitinase inhibitors share the imine functionality, either in acyclic or cyclic form.6 Moreover, several diverse mechanisms of action (MOA) related to chitin synthase have been described till today:
• ompetition of the analogues of UDP-N-acetylglucos- amine with the substrate.
• Prevention of the permeation of the substrate through the cytoplasmic membrane so that it is unable to reach the target enzyme.
• Inhibition of chitin biosynthesis and chitin deposition.
• Postpolymerization event, the translocation of chitin chains across the cell membrane.
• Stimulation of the immune system of the plant by inhibiting chitin-related enzymes, the plant elicitors.
The last one is probably the latest and one of the most interesting MOA. The present paper presents two quantitative structure−activity relationship (QSAR) discriminant equa- tions, designed by molecular topology (MT), as tools to identify the potential fungicides and new inhibitors of chitin formation. The MT paradigm consists in characterizing molecules through numerical descriptors called topological indices. These descriptors are based on simple and intuitive notions of a structure having to do with connections between different atoms in a molecule (molecular connectivity). The key elements are not geometrical or physical features of molecules, such as interatomic distances, bond angles or energies, and so forth (which usually play a main role in most QSAR approaches), but features such as the number of links between two atoms, the presence or absence of cycles, the possibility of connecting two particular atoms by a certain path, and so forth.8,9 It can be said that MT goes beyond standard QSAR approaches, allowing the generation of a huge number
