Abstract:
AbstractAs it has been already explained, it is very important for circular economies to minimize the wasted resources, as well as maximize the utilization value of the existing ones. To that end, experts can evaluate the materials and give an accurate estimation for both aspects. In that case, one might wonder, why is a decision support system employing machine learning necessary? While a fully automated machine learning model rarely surpasses a human’s ability in such tasks, there are several advantages in employing one. For starters, human experts will be more expensive to employ, rather than use an algorithm. One could claim that research towards developing an efficient and fully automated decision support system would end up costing more than employing actual human experts. In this instance, it is paramount to think long-term. Investing in this kind of research will create systems which are reusable, extensible, and scalable. This aspect alone more than remedies the initial costs. It is also important to observe that, if the number of wastes to be processed is more than the human experts can process in a timely fashion, they will not be able to provide their services, even if employment costs were not a concern. On the contrary, a machine learning model is perfectly capable of scaling to humongous amounts of data, conducting fast data processing and decision making. For power plants with particularly fast processing needs, an automated decision support system is an important asset. Moreover, a decision support system can predict the future based on past observations. While not always entirely spot on, it can give a future estimation about aspects such as energy required, amounts of wastes produced etc. in the future. Therefore, processing plants can plan of time and adapt to specific needs. A human expert can provide this as well to some degree, but on a much smaller scale. Especially in time series forecasting, it is interesting to note that, even if a decision support model does not predict exact values, it is highly likely to predict trends of the value increasing or decreasing in certain ranges. In the next sections, we are going to describe the four machine learning models that were developed and which compose the Decision Support System of FENIX. Section 8.1 describes how we predict the quality of the extracted materials based on features such as temperature, extruder speed, etc. Section 8.2 describes the process of extracting heuristic rules based on existing results. Section 8.3 describes how FENIX provides time-series forecasting to predict the future of a variable based on past observations. Finally, Sect. 8.4 describes the process of classifying materials based on images.

Abstract:
Though definitions may vary from source to source, the term alkaloid generally refers to members of a large set of naturally occurring, slightly basic (i.e., alkaline) nitrogen-containing organic compounds. Generally excluded from this group are amino acids, peptides, proteins, N-containing carbohydrates, and nitrogenous bases used in the construction of nucleotides. Though a small number are produced by animals or microorganisms, the vast majority of alkaloids are plant-produced compounds possessing a remarkably diverse range of structural features, from simple cycloaliphatic amines to highly complex polycyclic N-heterocycles. Some representative alkaloids are shown in Fig. 7.1. Alkaloid-containing plants and their extracts have been used by humans for thousands of years, mainly on the basis of their stimulant, therapeutic, or poisonous properties. References to plants containing compounds such as morphine (from opium poppies), strychnine (from seeds of the Strychnos nux-vomica tree), ephedrine (from the plant Ephedra chinensis), and coniine (from the poison hemlock plant) may be found in some of our earliest known writings. Today, it has been estimated that the health care of over 5 billion people worldwide benefits from the use of plant-based medicinal agents, many of which are alkaloids. With that in mind, it is worth noting concerns that deforestation, environmental damage, large-scale development, and unregulated harvesting programs may ultimately lead to the extinction of hundreds of known medicinal plants and perhaps even more whose medicinal properties have yet to be discovered, thereby endangering the prospects for future discoveries of new curative agents for the benefit of all humankind. As a scientific field, alkaloid chemistry itself dates back to the early 1800s with the first isolation of pure crystalline morphine from opium. This milestone achievement allowed the delivery of accurate, therapeutic doses of a drug that was immensely valuable for the relief of pain but which could also lead to fatal overdoses when administered from simple extracts of variable composition and strength. The subsequent rapid development of increasingly sophisticated techniques for the isolation and purification of the active components (often alkaloids) from many other medicinal plants essentially spawned the field of organic chemistry.

Abstract:
A greenhouse pot experiment was conducted to evaluate the phytotoxic effect of heavy metals (Zn, Cu, Ni, and Cr) on the growth (plant height, plant and seed weight) of Coriandrum sativum and uptake of metals. For this purpose, the polluted soil and sludge samples were collected from three sites of Moradabad: Karula nala (KS), Dhauri nala (DS), and Karula nala sludge (KSL). Metal content in the plant and soil was determined by AAS technique. The plants were also hydrodistilled using Clevenger apparatus and the extracted oil was analyzed by GC and GC/MS. The content of copper in KS and KSL, Zn in KS, Ni in DS and KSL, and Cr in KS was above the permissible limits according to Indian standards. Plant weight was significantly affected in the different soil samples. Among all the collected polluted soil and sludge samples, DS sample showed the highest metal accumulation, while in the KSL sample, the plant could not survive. The study revealed that coriander can be used to remediate the contaminated soil with economic return and metal free final product, essential oil.

Abstract:
Luffa cylindrica, popularly known as sponge gourd is a tropic and sub-tropical fibrous plant with fruits containing black seeds. The fruit is consumed by humans as a vegetable in many parts of Asia, while different parts of the plant are used for cosmetics and as medicine in many parts of the globe. The plant has been used in the treatment of many ailments including nose cancer, snake venom, wound healing, edema, enterobiasis, filaria, whooping cough, stomach upset, stomach pain and malaria. Many health-promoting compounds such as flavonoids (apigenin-7- glucuronide luteolin-7-O-β-D-glucuronide methyl ester, -O-feruloyl-β-D-glucose, luteolin-7-O-β-D-glucuronide methyl ester), phenolics acids (p-Coumaric, gallic, caffeic, chlorogenic), triterpenoids (oleanolic acid and echinocystic acid), saponins (Lucyoside A-M), tannins (catechin), ribosome-inactivating proteins (α- luffin), carotenoids (9 -cis neoxanthin, all-trans-lutein, all-trans-β-carotene), chlorophylls (chlorophyll a and b, pheophytin), cucurbitacin B and gypsogenin have been detected or isolated from different parts of the plants. Extracts of the plant and isolated compounds have wide spectrum pharmacological activities and have been shown to possess antiemetic, antidiabetic, antiviral, wound healing, anticancer, antipyretic, anti-inflammatory, antifungal, anti-bacteria, anthelmintic, hypoglycemic and antihyperglycemic, anti-inflammatory, antioxidant activity, and hepato-protective effects in animal models. However, further information is needed on its safety and mechanisms of action. The present article is an updated review of the ethnobotanical uses, pharmacological actions, phytochemistry, safety, and future application of Luffa cylindrica in translational medicine.

Abstract:
The above quote by the German poet, novelist, and painter Herman Hesse highlights the cultural significance of forests in nineteenth- and twentieth-century western culture as the ‘natural’ contrast to growing urban populations and industrial expansion. Hesse’s focus on the ‘ancient’ element of these environments is certainly valid in a tropical context, given that tropical forests are some of the oldest land-based environments on the planet, existing for over one thousand times longer than Homo sapiens (Upchurch and Wolf, 1987; Davis et al., 2005; Ghazoul and Shiel, 2010; Couvreur et al., 2011). This antiquity also makes them one of the richest and most diverse terrestrial ecosystems on the planet (Whitmore, 1998; Ghazoul and Shiel, 2010). Tropical rainforests, for example, contain over half of the world’s existing plant, animal, and insect species (Wilson, 1988). A significant portion of the developed world’s diet today originated in tropical forests—including staples such as squash and yams, spices such as black pepper, cinnamon, cloves, and sugar cane, and fruits including bananas, coconuts, avocados, mangoes, and tomatoes (Iriarte et al., 2007; Roberts et al., 2017a). Tropical forests also often provide ample freshwater for their inhabitants. However, despite popular perceptions of forests, and specifically tropical forests, as uniform, they are, in fact, highly variable across space and time. In tropical evergreen rainforests productivity is often primarily allocated to wood products, meaning that edible plants and animals for human subsistence have been considered lacking, or at least more difficult to extract, relative to more open tropical forest formations (Whitmore, 1998; Ghazoul and Shiel, 2010). Similarly, while evergreen tropical rainforests generally receive significant precipitation and freshwater, seasonally dry tropical forests are subject to sub-annual periods of aridity. Therefore, while archaeologists and anthropologists have tended to see ‘tropical forest’ as a uniform environmental block, it is important to explore the diversity within this category.

Abstract:
Alkamides, or alkylamides, are fatty acid amides produced by plants from the genera Echinacea, Acmella, Spilanthes, and Heliopsis among others. Alkamides contain varying head groups, an amide moiety, and a fatty acid tail with varying numbers of carbons and double and triple bonds. Extracts from these plants have been used worldwide by native peoples for the treatment of numerous medical disorders, including bacterial and viral infections, inflammation, liver and kidney disorders, and pain. In vitro, these molecules display a variety of different activities depending on the cell type tested. Studies with neurons, macrophages and mast cells have revealed interactions between alkamides and a number of different cells surface receptors and intracellular signaling molecules. Generally, the alkamides have been found to exert suppressive effects, inhibiting cellular activation. In this report we introduce the structure of alkamides and review their effects in a number of different cellular systems. We also describe structure:function studies that have been performed with alkamides. While these studies have not as yet revealed general rules for alkamide activity, interesting insights have been revealed. The stage is set for the development of synthetic, designer alkamides with targeted in vivo activities.

Abstract:
Abstract In the Gulf Cooperation Council region, approximately 70% of the thermal power plants are in a simple cycle configuration while only 30% are in combined cycle. This high simple to combined cycle ratio makes it of a particular interest for original equipment manufacturers to offer exhaust heat recovery upgrades to enhance the thermal efficiency of simple cycle power plants. This paper aims to evaluate the potential of incorporating costly-effective new developed heat recovery methods, rather than the complex products which are commonly available in the market, with relevant high cost s

Abstract:
We define an admissibility condition for abstractions expressed using angelic semantics and show that these conditions allow us to accelerate planning while preserving the ability to find the optimal motion plan. We then derive admissible abstractions for two motion planning domains with continuous state. We extract upper and lower bounds on the cost of concrete motion plans using local metric and topological properties of the problem domain. These bounds guide the search for a plan while maintaining performance guarantees. We show that abstraction can dramatically reduce the complexity of sea

"Nowadays we are witnessing an increased interest in phytotherapy and implicitly for herbal products that have lower side effects. One medicinal plant whose popularity has decreased significantly in recent years is Lythrum salicaria L., loosestrife, known in Romanian traditional medicine for its beneficial effects against gastrointestinal diseases. The aim of this study is to evaluate the biological activity of three different extracts (aqueous, alcoholic, acetonic) from the flower tips of Lythrum salicaria L. using the BSLA (Brine Shrimp Lethality Assay) test and the antimicrobial activity of

Abstract:
Salinity is considered as major environmental challenge that affects crop growth and productivity. This study investigated the application of Haodule univervis seagrass liquid extract on bell pepper (Capsicum annuum L.) under salt stress conditions. The salinity treatments were applied by irrigating bell pepper plants with 0, 50, 100, 150, and 200 mM/l of NaCl with four replications. The bell pepper plants were divided into two groups: one group was sprayed with seagrass extract, and the other group was sprayed with distilled water. The salt treatment was applied at every 10 days interval for

Abstract:
This work concerns the dynamic modeling of closed cycle gas turbine with a nuclear heat source. The paper focuses on a particular safety question: the consequences of a hypothetical large break accident. A model of the whole circuit of the Gas Fast Reactor (GFR) has been built using a specific turbo-machine description. The compressor modeling presented in a separate paper [1] is completed with turbine modeling. Transient simulation results point out the importance of the location of the pipe rupture: in some detailed cases, back flow through the core can occur during the first seconds. The ot

Abstract:
A type of coupled steam–gas turbine plant is proposed here. It is composed of a regenerative extraction steam turbine and a steam injected gas turbine. Extracted steam of the regenerative extraction steam cycle is not used to heat water through the regenerative feed–water heater as in conventional plant, but injected into a gas turbine to augment the output of the gas turbine, while the exhaust gas of the gas turbine now displaces the extracted steam to heat the feed water of the steam turbine plant. The proposed repowering turbine plant has two merits: the further utilization of extraction st

Abstract:
This paper aims at evaluating the possible upgrading of an existing district heating plant for production of electricity and pellets. The evaluation is carried out by optimizing the alternatives from the economic, thermodynamic and environmental point of view. In order to examine how the design can be optimized, a detailed model of the process has been elaborated using ASPEN Utilities and Matlab optimization toolbox. The parameters of the polygeneration plant have then been varied in order to examine how optimal economic benefit can be extracted from the biomass streams whilst still meeting th
