TL;DR: In this paper , Chaotic Spotted Hyena Optimization (CSHO) was proposed to improve and intensify the conventional approach and compared with some well-known published approaches using standard data.
Abstract: ABSTRACT Power system network is growing day by day as per the increased demand due to technological development around the globe. The increased power demand needs optimized planning for all the sections of power system. Economic dispatch is one of the important areas in which new optimization techniques can add to the overall improvement in the power system planning. Recent technological improvement in microgrids results in economic and efficient operation considering both conventional and non-conventional methods of generation. This paper highlights the optimal scheduling requirement in the advanced power system control by introducing a new proposed metaheuristic hybrid approach, i.e., Chaotic Spotted Hyena Optimization (CSHO). The proposed approach improves and intensifies the conventional approach and the results obtained are compared with some well-known published approaches using standard data. The CSHO is implemented on an islanded microgrid having five distributed generators out of which three are conventional generators and two are renewable sources. Three objectives are tested on the microgrid-(1) Economic scheduling, (2) Environmental emission and (3) CEED for Microgrid and the results of proposed approach are tested in four scenarios and compared with the PSO, DE, SOS, GWO and WOA approaches. The result achieved from the proposed approach is remarkable over previous approaches and showing enhanced economic operation, which are verified and presented in different sections of paper.

TL;DR: In this article, a qualitative and quantitative study of elephant foot yam corms during storage was performed and the results showed that salt and alum treated tubers significantly decreased oxalate content, both soluble and insoluble.
Abstract: The presence of oxalate and acridity has led to gross underutilization of Amorphophallus paeoniifolius, a salubrious tuber, consumed traditionally as a vegetable. Therefore, as a means to overcome oxalate and acridity problem, treating the corms by alum and salt and then cooking resulted low oxalate content. Elephant foot yam significantly decreased (p < 0.05) the oxalate content, both soluble and insoluble. This study is totally based on qualitative and quantitative study of elephant foot yam corms during storage. On the basis of nutritional value two cultivars were used at maturity stage for making cubes and evaluated their oxalate content at 60 days intervals. The ranges of oxalate contents were found to be: water soluble oxalate 8.11-22.93 mg/100g, total soluble oxalate 10.01-28.51 mg/100g, calcium oxalate 0.63-9.38 mg/100g and total oxalate 10.86-31.04 mg/10g during storage. The mean soluble oxalate content was safe from the viewpoint of accumulation of urinary oxalate leading to kidney stones. Therefore, salt and alum treated tubers can certainly enhance its consumption pattern without any possible deleterious effect (renal functioning and mineral bioavailability) on human population. This information will provide scientist with the ability to develop quality product having high nutrition and better anti-nutritional profile.

TL;DR: An 18-year-old female patient presented with lump hypogastrium since one month, initially small in size but increased progressively to attain the present size, and complained of non-specific, non-localized abdominal pain which was chronic, dull aching in nature, and nonradiating.
Abstract: An 18-year-old female patient presented with lump hypogastrium since one month. Lump was initially small in size but increased progressively to attain the present size. She also complained of non-specific, non-localized abdominal pain which was chronic, dull aching in nature, and nonradiating. It was mild in severity with no aggravating or relieving factors. Bladder and bowel habits were normal. She had an irregular menstrual cycle of 30–60 days, 1–2 days duration and scanty flow. She had no history of previous medication or hospitalization. On examination, two discrete tender lumps, 7–9 cm in size and firm in consistency, and well-defined margins present in hypogastrium. Per vaginal examination could not be performed due to denial of consent due to virgin status. All laboratory investigations were within normal limit except hemoglobin which was 5.9 mg% and low T3 0.10 ng/ml (normal 0.7–2.0 ng/ml), low T4 1.2 lg/dl (normal 5.5–13.5 lg/dl), and high TSH 102 llu/ml (normal 0.3–5.0 llu/ml) levels. CA 125 and other tumor markers were within normal limits. Ultrasonography at the time of admission showed bilateral enlarged ovaries of size 15.22 9 8.26 cm(Rt. Ovary) and 11.82 9 6.24 cm (Lt. ovary) with multiple cysts of varying sizes in both ovaries, giving a classical ‘spoke wheel-like appearance.’ A diagnosis of bilateral ovarian cysts was made, and diagnostic laparoscopy was planned for further management. On pre-anesthetic cardiopulmonary evaluation, pericardial effusion was suspected. Hence, cardiology opinion was taken and subsequent echocardiogram revealed massive pericardial effusion. Then, on the basis of previous findings and echocardiogram put together, a diagnosis of spontaneous Singh A. (&), Senior Resident Singh K., Ex.Senior professor and Head Of Department Khandelwal R.

TL;DR: It is hypothesize that a system utilizing a murine light-reporter mammary tumor cell line and near-infrared nanoparticles (NIR-NP) can be used to quantify response to therapy and determine fate of nanoparticles following photothermal ablation.
Abstract: Multifunctional theranostic nanoparticles hold promise for enabling non-invasive image guided cancer therapy such as photothermal therapy. Human breast tumor models in which response to image guided therapy can quickly and non-invasively be determined are needed to facilitate translation and application of these technologies. We hypothesize that a system utilizing a murine light-reporter mammary tumor cell line and near-infrared nanoparticles (NIR-NP) can be used to quantify response to therapy and determine fate of nanoparticles following photothermal ablation.

TL;DR: A comprehensive review of current research activities that center on the shape-controlled synthesis of metal nanocrystals, including a brief introduction to nucleation and growth within the context of metal Nanocrystal synthesis, followed by a discussion of the possible shapes that aMetal nanocrystal might take under different conditions.
Abstract: Nanocrystals are fundamental to modern science and technology. Mastery over the shape of a nanocrystal enables control of its properties and enhancement of its usefulness for a given application. Our aim is to present a comprehensive review of current research activities that center on the shape-controlled synthesis of metal nanocrystals. We begin with a brief introduction to nucleation and growth within the context of metal nanocrystal synthesis, followed by a discussion of the possible shapes that a metal nanocrystal might take under different conditions. We then focus on a variety of experimental parameters that have been explored to manipulate the nucleation and growth of metal nanocrystals in solution-phase syntheses in an effort to generate specific shapes. We then elaborate on these approaches by selecting examples in which there is already reasonable understanding for the observed shape control or at least the protocols have proven to be reproducible and controllable. Finally, we highlight a number of applications that have been enabled and/or enhanced by the shape-controlled synthesis of metal nanocrystals. We conclude this article with personal perspectives on the directions toward which future research in this field might take.
