Abstract:
Choline salicylate (CS) as a derivative of acetylsalicylic acid is commonly used in different drug forms. In medicine, it is applied topically to inflammation of the oral cavity mucosa and in laryngology. However, this substance in the form of an ionic liquid has not been investigated enough. There are no literature studies on stability tests constituting a stage of pre-formulation research. HPLC (Nucleosil C18, 4.6 × 150 mm, 5 μm; methanol-water-acetic acid 60:40:1, 230 nm or 270 nm) and UV (276 nm) methods for the determination of CS in 2% (g/mL) aqueous solutions were developed.

Abstract:
AbstractForests play a vital role in combating climate change and mitigating its effects. In the Hindu Kush Himalaya (HKH), they are an important source of livelihood for the region’s growing population. With forest degradation and deforestation increasing, it has become all the more necessary to have a reliable climate resilient forest management system. At present, lack of precise information on forest degradation and the impacts of climate change on forest ecosystems hinder the conservation, planning and management of forest ecosystems in Nepal. We attempt to tackle this issue in collaboration with Department of Forests and Soil Conservation (DoFSC), Nepal, by providing scientific and reliable data on vulnerability of forests to anthropogenic factors and climate change using geospatial tools and techniques. We introduced a two-way multitier approach in Nepal to support the identification and implementation of adaptation and management strategies with special focus on forest ecosystems. It aims to reduce the vulnerability of forests to climate change and the degradation of forest ecosystems due to anthropogenic drivers. We used multispectral satellite datasets, data on climate trends and projections, and published data on extraction of forest resources in the study area. We then used data mining to quantify the influence of temperature and precipitation on functioning of forests by using MODIS data of net primary productivity, leaf area index, evapotranspiration and climatic trends and projections data. Finally, we overlayed the forest degradation map on forest climate sensitivity map to identify the hotspots of degradation and sensitivity needing immediate attention. These hotspots are defined as “adaptation footprints”, which help decision makers to prioritize their activities within their district. Most of the forest ecosystems in mid-western and far-western Nepal are highly sensitive to observed and predicted impacts of climate change, which need immediate prioritization and management. The products of this study are accessible through a web-based decision support tool, which will help decision makers at district and province level to prioritize the activities of forest management.

Abstract:
This chapter deals with the application of Higher Order Neural Networks (HONN) on the modeling and simulation of two processes commonly used to produce gas with energy potential: anaerobic digestion and gasification. Two control strategies for anaerobic digestion are proposed in order to obtain high biomethane flow rate from degradation of organic wastes such as wastewater. A neurofuzzy scheme which is composed by a neural observer, a fuzzy supervisor, and two control actions is presented first. After that, a speed-gradient inverse optimal neural control for trajectory tracking is designed and applied to an anaerobic digestion model. The control law calculates dilution rate and bicarbonate in order to track a methane production reference trajectory under controlled conditions and avoid washout. A nonlinear discrete-time neural observer (RHONO) for unknown nonlinear systems in presence of external disturbances and parameter uncertainties is used to estimate the biomass concentration, substrate degradation, and inorganic carbon. On the other side, a high order neural network structure is developed for the process identification in a gasification reactor; the gas, composed mainly of hydrogen and carbon monoxide (synthesis gas or syngas), is produced from thermo chemical transformation of solid organic wastes. The identifier is developed in order to reproduce a kinetic model of a biomass gasifier. In both cases (biological and thermo chemical processes), the Extended Kalman Filter (EKF) is used as a training algorithm. The proposed methodologies application is illustrated via numerical simulations.

Abstract:
A novel keystroke biometric system for long-text input was developed and evaluated for user identification and authentication applications. The system consists of a Java applet to collect raw keystroke data over the Internet, a feature extractor, and pattern classifiers to make identification or authentication decisions. Experiments on more than 100 participants investigated two input modes—copy and free-text—and two keyboard types—desktop and laptop. The system can accurately identify or authenticate individuals if the same type of keyboard is used to produce the enrollment and questioned input samples. Longitudinal experiments quantified performance degradation over intervals of several weeks and two years. Additional experiments investigated the system’s hierarchical model, parameter settings, assumptions, and sufficiency of enrollment samples and input-text length. Although evaluated on input texts up to 650 keystrokes, the authors found that input of 300 keystrokes, roughly four lines of text, is sufficient for the important applications described.

Abstract:
In recent years, the presence of organic pollutants has received great attention due to their effects on public health and biota. Within this set of compounds, a new range of compounds that are characterized by their high persistence and low degradation have been identified, called Emerging Compounds. Emerging pollutants include a wide variety of products for daily use of different structures, domestic and industrial applications, such as: pesticides, industrial and personal hygiene products, hormones, and drugs, most of which are toxic, persistent and bioaccumulative. A characteristic of these types of pollutants is that current wastewater treatment plants are unable to remove them; they are designed to remove organic matter and nutrients in higher concentrations. In Mexico there is little information on the concentration levels of these compounds, due to the lack of public policies aimed at providing resources to institutions and researchers trained to carry out this type of study. On the other hand, the technological infrastructure of the wastewater treatment plants is insufficient for the country’s demand. This situation represents one of the greatest challenges for the authorities responsible for the management of water resources, in the immediate time if it is intended to preserve said resource and therefore take care of the health of the population.

Abstract:
The purpose of agricultural enterprises is to improve the quality of domestic products, their competitiveness, food security, development of genetics and breeding, reproduction of land fertility, digitalization, which is impossible without economic transformation, management decisions, the introduction of technological processes for the long-term development of agriculture. The agro-industrial complex plays an important role in the development of the economy as a whole and performs a social function, ensures food security of regions and employment of people living in rural areas, so the quality of life depends on the formation of economic development of agriculture. Methodology. A scientific approach to solving problems allows to model possible situations and avoid negative consequences due to incorrect strategic policy of the organization. Construction of a matrix of strategic qualitative analysis based on methodological approaches to assessing the characteristics, properties of enterprise development strategy and implementation of economic development strategies for agricultural enterprises based on the use of analysis, which provides priority identification of strengths and weaknesses, potential opportunities and threats, languages that can be used to formulate the strategy of agricultural enterprises, is an important step in building a strategy. Results. In a competitive market, it is impossible to succeed by providing low-quality services or offering low-quality goods. Before developing business management processes, it is necessary to develop a functional strategy. Strategic analysis, which gives a realistic assessment of their own resources and capabilities in relation to the state and needs of the environment for agricultural enterprises and helps to make a rational choice of strategies from a variety of options. Practical implications. Strategies at any level usually do not have the resources or ability to use resources in a way that provides full confidence in success. Therefore, during the qualitative strategic analysis, in our case, we have determined that the miscalculations in the opening of the land market (no restrictions for buyers, price formation, protection mechanisms against speculative resale of land), war, political and economic crisis in Ukraine, miscalculations in the regulation of the industry, deterioration of land quality, loss of land value due to the development of alternative production, further decline in margins, degradation of the sector, loss of yield potential due to soil degradation resulting from intensive production, raiding, high cash turnover, fraudulent schemes, counterfeiting products, pressure from law enforcement agencies are threats to building an effective strategy for agricultural enterprises, it is necessary to take into account the strengths and weaknesses of agricultural enterprises and on the basis of opportunities to achieve economic growth.

Abstract:
Plasmin and leucocyte elastase are regarded as the two medically most important fibrin(ogen)-degrading proteolytic enzymes. There is, however, a considerable difference in information available about the cleavage specificities and fragmentation pathways of these two enzymes. Degradation by plasmin has been studied already for a long time in great detail so that now the time course of the degradation, the cleavage sites and the functional properties of many fragments are well known. In contrast, relatively little is known about the degradation by leucocyte elastase, except that the overall clea

Abstract:
The desire to enlarge the flight envelope of tactical aircraft and provide enhanced maneuvering capabilities has led to the use of forces and moments produced by the propulsion system to directly influence aircraft dynamics. This coupling between propulsion and flight dynamics is significant enough that traditional techniques for control system design and analysis are either conservative or inaccurate. An integrated approach is required in order to obtain an overall system that provides stability and performance with minimum pilot workload. The authors propose a solution that integrates existi

Abstract:
This paper describes a probabilistic site identification analysis performed by BNL, using the free-field earthquake motions recorded at the NUPEC test site. The BNL analysis was intended to provide adequate characterization of the soil properties for the test site to be used for the SSI analyses. The free-field data were provided by NUPEC. The methodology employed in the BNL probabilistic analysis of site identification includes the Monte Carlo process in conjunction with equivalent linear convolution analyses for generating a large number of site profiles for use in convolution studies from w
