This article investigates the geopolitics of the energy transition era, concentrating on China's solar photovoltaic (PV) industry. Authors have noted that the rise of renewables is changing the geopolitical landscape of world energy systems, but these new energy sources carry their own technical characteristics and geopolitical implications. Bearing this in mind, this research answers the questions: What are the structural factors that facilitate China's use of renewable energy to achieve political goals, and what are their implications? In order to analyze the data, I devise an analytical framework based on the energy statecraft literature and contrast rival explanations, particularly the "prosumer theory" and the premise of less geopolitical interdependence in a renewable-centered world. I show that asymmetric interdependence in the solar PV sector is already a reality. China's solar PV industry is a case that suffices all conditions (centrality in industrial capacity, market share, and companies' compliance, but to a lesser extent in critical materials and technological endowments) in the solar PV sector to devise effective strategies aimed at reaping benefits out of its asymmetric interdependence with the rest of the world.
Physiological and Molecular Characterization of Cephaleuros virescens Occurring in Mango Trees

The objective of this work was to accomplish the isolation, molecular identification and characterizing the physiology of the causal agent of the algal spot in mango trees. For this purpose, the pathogen growth was assessed in different culture media, with subsequent observation and measurements of the filamentous cells. The molecular identification was made using mycelium obtained from leaf lesions and pure algae colonies grown in culture medium. Descriptions based on DNA sequencing indicated that the algae is Cephaleuros virescens. The algae must be isolated primarily in liquid medium for further pricking into agar medium. The highest mycelial growth average in Petri dishes occurred when the algae were grown in Trebouxia and BBM. Trebouxia enabled larger cells in the filamentous cells when compared to other culture media.

Usually considered as one of the future solutions for grid connection of photovoltaic systems, module integrated converters were already the focus of several researches and projects. Most of the proposed approaches relied so far on the use of high frequency step-up transformers either in isolated operation or integrated in isolated dc-dc topologies. This paper analyses the possibility of using non-isolated topologies to achieve the necessary high-voltage gain for grid connection. Several circuits were analyzed and the best suited one for the current application was evaluated and optimized. Experimental results are presented in the final section.
LCL Filter design for grid-connected NPC inverters in offshore wind turbines

This paper deals with the analysis, design and optimization of a LCL filter topology to connect a 7MW NPC inverter to the grid. Following the requirements based on the IEEE 519-1992 recommendation and the German Guideline VDEW, simulation results were evaluated in order to access the performance of the proposed filter and the quality of the current injected into the grid.

This essay explores the awareness of the loss of a sense of community at every level in Western societies. Using an incident in a Lisbon subway involving a grandfather and his grandson, I argue the need to move the child away from the “center” and back to his communities. I contest and deconstruct child-centered discourse and affirm the importance of a community discourse for the development of Dewey`s “whole child.” Communities are a common good, complex wholes, ethical sites, places for an intricate world of interactions. Community life provides a high order of moral and intellectual reasoning. The musical metaphor of an orchestra is used to demonstrate the need for a revitalized community where the child is a central part but not at the “center.”

Acceptance and the probiotic viability of aninnovative non-dairy frozen açaí (Euterpe oleracea, Mart.)dessert supplemented and not supplemented with inulinduring a shelf-life of 84 days at −18oC were investigated. Desserts containing and not containing probiotic Lactobacillusacidophilus La-5 and Bifidobacterium animalis Bb-12 andinulin were produced, resulting in 4 mixes of frozen açaí:control (M1), pro (M2), pre (M3), and synbiotic (M4). Sensory acceptability scores and probiotic counts wereobtained during 84 days of storage. Inulin, a key factor forproduct approval, significantly (p<0.05) increased overallproduct acceptance of both M3 and M4, compared withM1. La-5 viability was above 7 log CFU/g for both pro andsynbiotic desserts. Bb-12 counts were above 6 log CFU/gonly for M4. All frozen açaí desserts were suitable forprobiotic delivery and were accepted by consumers. Addition of inulin is recommended both for increasingacceptance and for the synbiotic potential.
Ossifying fibroma in the maxilla and orbital floor: report of an uncommon case
Diogo de Vasconcelos Macedo,Gabriely Ferreira,Eduardo Hochuli Vieira,Marcelo Silva Monnazzi 대한구강악안면외과학회 2020 대한구강악안면외과학회지 Vol.46 No.3
Benign fibro-osseous lesions occur when normal bone is replaced by cellular fibrous connective tissue and mineralized structures. One rare type of these lesions is the ossifying fibroma (OF). The aim of this study is to report an unusual case of OF in a 57-year-old female. Physical examination showed facial asymmetry without any tenderness, fluctuation, ocular pain, or ophthalmoplegia. Imaging exams revealed a solid mass involving the left maxilla and orbital floor. Surgical resection was performed without any complications or sequelae, and the histopathological results confirmed OF. Although recurrence is rare in this condition, the patient remains under follow-up.

Spinach (Spinacia oleracea) cytosolic fructose-1,6-bisphosphatase (FBPase) was purified and the final preparation of protein has a specific activity of about 45 units/mg protein and a single band of molecular mass of 39 kDa. Polyclonal antibody against the protein did not cross-react with chloroplast FBPase, but showed strong cross-reactivity with all plant cytosolic FBPases tested. Studies of the FBPase expression characteristics at early stages of development demonstrated that it was controlled at both the transcriptional and translational levels, and its mRNA was detected even in etiolated cotyledons. This suggests that the expression is not light-inducible. A single transcript was detected in all spinach tissues tested. Western blot analysis revealed two protein bands in the etiolated cotyledons: one was the same size as that present in the mature leaf, and the other slightly smaller. A high enzyme activity was detected in etiolated cotyledons, especially compared to protein levels in Western blots. Expression of the cytosolic FBPase gene during leaf development showed no change in the steady-state level of mRNA, but the protein level and enzyme activity were higher in mature leaves than in young ones, suggesting that the increase in FBPase activity during development is due to an increase in protein synthesis. Young roots showed low enzyme activity, but an unexpectedly high activity was detected in old fiber roots.
