Abstract
Mesenchymal stroma/stem cells (MSCs) exist in adult tissues, such as adipose tissue and bone marrow, and differentiate into cells of multiple lineages. In previous studies, we found that MSCs differentiate into steroidogenic cells by forced expression of steroidogenic factor 1 (SF-1)/adrenal 4 binding protein (Ad4BP), the master regulator of steroidogenesis and differentiation of pituitary gonadotrophs, adrenal glands, and gonads. In this study, SF-1/Ad4BP-induced steroidogenic cells derived from mouse adipose tissue–derived MSCs (ADSCs) were implanted under the kidney capsule of bilateral adrenalectomized (bAdx) mice. bAdx mice did not survive after 7 days. However, 4 of 9 bAdx mice implanted with SF-1/Ad4BP-induced steroidogenic cells, 1 of 10 bAdx mice transplanted with control ADSCs, and bAdx mice transplanted with an adrenal gland survived for 30 days. Plasma corticosterone levels in bAdx mice implanted with SF-1/Ad4BP-induced steroidogenic cells and control ADSCs were 5.41 ± 2.26 ng/mL (mean ± SEM) and undetectable at 7 days after implantation, respectively. After removal of the kidney bearing the graft from the surviving mice at 30 days after implantation, plasma corticosterone was not detected in any of the samples. Immunohistochemical staining revealed SF-1/Ad4BP-positive cells under the capsule of the kidney. Although we performed an adrenocorticotropin (ACTH) loading test on bAdx mice implanted with SF-1/Ad4BP-induced steroidogenic cells, ACTH responsiveness was not observed. Implantation of steroidogenic cells derived from ADSCs into bAdx mice increased the basal plasma corticosterone level and extended the survival of bAdx mice, suggesting the capability of restoring steroidogenic cells by cell transplantation therapy for adrenal insufficiency.

Published: January 2020

The alkalinity of sintered ore has an important impact on the quality, output, and energy consumption of blast furnace smelting, and there is an urgent need for a method for accurate quantifying of the alkalinity of sintered ore. The present work explores the combination of the laser-induced breakdown spectroscopy (LIBS) technique and random forest (RF) based on principal component analysis (PCA) and variable importance for the quantitative analysis of the alkalinity of sintered ore. Sixteen sintered ore samples were used in this study, and the characteristic lines of LIBS spectra for sintered ore samples can be identified based on the National Institute of Standards and Technology (NIST) database. At first, abnormal spectra are identified and rejected by PCA coupled with Mahalanobis distance (MD). Then, the input variable for the RF calibration model is optimized according to the variable importance threshold obtained by the RF model, and two RF model parameters of

are determined by out-of-bag estimate. Finally, the PCA-VI-RF model is built under the optimal model parameters. In order to verify the predictive ability of the quantitative model, the PCA-VI-RF model prediction results were compared with the RF model, partial least-squares model, and least-squares support vector machine model. The result demonstrated that PCA-VI-RF shows better analytical performance than other methods. Compared with the RF model with the original spectrum as input, the averaged relative errors of test results decreased from 5.82% to 3.94%, coefficients of determination (

) of the test set increased from 0.8957 to 0.9814, and the root mean square error decreased from 0.1502% to 0.0860%. The speed of modeling and prediction has also been greatly improved, and the modeling time was reduced from 4675.56 to 16.86 s. The stability of the PCA-VI-RF model was verified by the relative standard deviation (RSD) of the test data prediction results, and the RSD reached below 4.74%. This study shows LIBS combining PCA-VI-RF is an effective method for accurate quantification of the alkalinity of sintered ore. It has great significance for the potential application of real-time online analysis of the alkalinity of sintered ore.
Enhanced second-harmonic generation from L-shaped AlGaAs nanoantennas
Authors: Zeng Tao , Guo Ling , Xu Long , Han Tiancheng 
Published: January 2020

Nanostructured materials offer many advantages over bulk materials in nonlinear optical phenomena. For example, the subwavelength scale allows the neglect of phase-matching issues. The ability to control tight confinement and large resonant enhancement of electromagnetic fields also results in higher nonlinear frequency conversion efficiencies than bulk materials. Compared with plasmonic nanostructures, high-index dielectric nanostructures render larger mode volumes and show great promise for enhanced nonlinear optical processes. In this work, we present resonantly enhanced second-harmonic generation from L-shaped AlGaAs nanoantennas. By tuning the nanostructure thickness, arm length, and width, the overlap of resonances at fundamental and second-harmonic wavelengths can be achieved using any pump wavelength in a broad near-infrared spectral region. We predict SHG efficiency exceeding

Authors: Busingye John 
Published: January 2020

The study mainly set out to investigate the factors that influence loan delinquency bySME owners in Uganda. SME ownersin Mbarara Municipality, South West Uganda provided conceptual setting of the study. This paper contributes to the body of knowledge by determining the local business context influencing loan delinquency among SME owners.
The study fixated on thefactors that influence loan delinquency by SME owners in Uganda with focus on what SACCOs put into consideration in order to categorize an SME as suitable for micro-lending. The study engaged descriptive research design, where 20 questionnaires were administered to SME owners and detailed discussions of the questions conducted with 6 key informants in the SME sector. The study was grounded on David McClelland’s Acquired Needs theory and the Rational Choice theory in helping to understand the subject under investigation. The study further adopted Krejcie and Morgan's (1970) sample size determination methodology to select the respondents. Data was analysed using SPSS version 20, thematic and content analysis.
The study findings show that majority of the respondents were male with secondary level of education, majority of the SME entities had been in operation for six years and above and their ability to manage loans was boosted by education, skills and experience. While the majority of the SME owners are accessing and utilizing loan services from the SACCOs, more than half of them have ever been in delinquency over their loan contract. The study recommends that the SME owners learn how to plough back their profits into their business, conduct sound business research so as to increase their operational capital and skills in order to expand and grow their projects. The study concluded that the SME industry is a fertile ground for investment for Uganda, SME owners, and SACCOs.
On Unnatural Narrative in Post-9/11 Fiction Flight
Authors: Ni Zengxin 
Published: January 2020

In the wake of innumerable and insightful studies on the unnatural narratology at home and abroad, it develops into a post-classical narratology that is comparable to female narratology, rhetoric narratology, and cognitive narratology. Taking the native American writer Sherman Alexie’s Flight as its central concern, the essay attends to explore the unnaturalness of the novel and further elaborates on its thematic meaning. In Alexie’s Flight, as a post-9/11 fiction, its unnaturalness can be explored by such elements as unnatural storyworlds, unnatural minds and unnatural acts of narration. The intentional violation of conventional narration further highlights the hero’s crisis and reconstruction of his identity in the post-9/11 world changed with the miserable memory in his childhood, his sublimation from terrorism to pacifism during his time travel and the regain of love in his final foster family, which consequently contributes to the final change of his appellation from “Zits” to “Michael”.
Quintilian’s Institutes of Oratory: Classical Rhetoric and English Language Education in China
Authors: Lucas Stephen E. 
Published: January 2020

Abstract
Well known to students of rhetoric, classics, and the history of education, Quintilian’s Institutes of Oratory also merits the attention of EFL teachers and scholars who deal with public speaking and written composition. Although created in ancient Rome 2,000 years ago, the Institutes is replete with insights that are as applicable today as in Quintilian’s time. After providing historical background on Quintilian and his masterwork, this article examines his comprehensive program of speech education, his explication of the symbiotic relationship between speech and writing, and his notion of the good person speaking (and writing) well as the ideal of ethical communication. In the process, it touches upon numerous issues germane to English language educators in China and to EFL teaching and research in general.
A Corpus-Based Comparative Study on Lexical Bundles in Native and Chinese Scholars’ English Abstracts—Taking Linguistics and Chemistry as an Example
Authors: Liu Jia , Lu Yuqing 
Published: January 2020

AbstractBased on self-established corpora, the study systematically explores structural and functional similarities and differences of four-word lexical bundles in native and Chinese writers’ English abstracts both in chemistry and linguistics from the interdisciplinary and intradisciplinary viewpoint. The results show that disciplinary features are found in the use of lexical bundles. Besides, most bundle differences found in abstracts by English native writers are also found in those written by Chinese scholars, indicating that Chinese scholars have developed an awareness of their discipline. In addition, both structurally and functionally, the lexical bundles in Chinese writers’ abstracts are similar to those of native writers in linguistics while divergent in chemistry.

Published: January 2020

Abstract
The Jordan–Hölder theorem is a general term given to a collection of theorems about maximal chains in suitably nice lattices.
For example, the well-known Jordan–Hölder type theorem for chief series of finite groups has been rather useful in studying the structure of finite groups.
In this paper, we present a Jordan–Hölder type theorem for supercharacter theories of finite groups, which generalizes the one for chief series of finite groups.

Published: January 2020

AbstractIn this research, the photocatalytic degradation performance in a commercial low-density polyethylene (LDPE) film was investigated in the presence of zinc oxide (ZnO) nanoparticles grafted with two amounts of polyacrylamide. Fourier-transform infrared spectroscopy (FTIR) besides thermogravimetric analysis (TGA) test results reinforced the successful grafting of polyacrylamide to the extent of 10 and 39 wt.% on the ZnO nanoparticles. The photocatalytic degradation of the films under ultraviolet (UV) radiation was evaluated by characterizing the mechanical properties, weight loss, and morphology. The UV absorption and emission for ZnO nanoparticles were increased after grafting with 10% polyacrylamide. The tensile strength of the nanocomposite films increased with the incorporation of nanoparticles. The presence of ZnO nanoparticles in LDPE films increased the rate of degradation after 200 h of irradiation. The polyacrylamide grafting improved the dispersion of ZnO particles in LDPE matrix, whereas the increase of grafting extent from 10 to 39 wt.% reduced the photocatalytic performance of ZnO nanoparticles.
Investigations on the Machining Characteristics of Silica-Phenolic Ablative Tiles Bonded to a Metal Substrate
Authors: Sooraj V. S. , Chakravarthy P. , Danish H. , Mohan Kumar L. 
Published: January 2020

Abstract
Thermal protection systems are of great importance to the aerospace industry as they prevent the structural member from being heated up to a great degree, which otherwise may lead to undesired failures. “Silica phenolics” is one such ablative composite that is widely used for rocket nozzle and re-entry applications. Though the composite is fabricated to a near net shape, secondary processing, such as machining, becomes inevitable for maintaining dimensional tolerances. Usually, these composites are bonded to a structural member that needs protection from high temperatures. Subsequently, these composites, after bonding to the substrate, are machined to the required geometries using single-point cutting tools to suit the functional requirements. The present work addresses the single-point machining of ablative tiles bonded to a metallic mandrel to simulate the real-time conditions of machining ablative composites bonded to a rocket nozzle. The present work also adopts a special cutting strategy that varies the uncut thickness on different segments of a circular workpiece during its rotation, which simulates reality. Variation of cutting forces was captured at each of these ablative composite segments for different cutting speeds and depth of cut to understand the influence of uncut thickness and width of cut. Possible hypotheses on the mechanism of material removal were analyzed to understand the defects that would arise out of cutting edge interaction with the ablatives. The study revealed that the cutting forces during machining were much lower, and the debonding of the ablatives from the substrate was not observed. The results of the shear lap test also indicated that the debonding force was comparably higher than the observed cutting forces.
Medial Prefrontal Cortex Neural Plasticity, Orexin Receptor 1 Signaling, and Connectivity with the Lateral Hypothalamus Are Necessary in Cue-Potentiated Feeding

Published: January 2020

Cognitive processes contribute to the control of feeding behavior and help organism's survival when they support physiological needs. They can become maladaptive, such as when learned food cues drive feeding in the absence of hunger. Associative learning is the basis for cue-driven food seeking and consumption, and behavioral paradigms with Pavlovian cue-food conditioning are well established. Yet, the neural mechanisms underlying circuit plasticity across cue-food learning, cue memory recall, and subsequent food motivation are unknown. Here, we demonstrated the medial prefrontal cortex (mPFC) is a site of learning-induced plasticity and signaling of the neuropeptide orexin within the mPFC mediates cue potentiated feeding (CPF). First, using a marker of neuronal activation,c-fos,we confirmed that the mPFC is activated during CPF. Next, to assess whether the same mPFC neuronal ensemble is activated during cue-food learning and later CPF, we used the Daun02 chemogenetic inactivation method inc-fos-lacZtransgenic male and female rats. Selective inactivation of the mPFC neurons that were active during the last cue-food training session abolished CPF during test, demonstrating that the mPFC is a site of plasticity. We postulated that integration of food cue memory and feeding motivation requires mPFC communications with lateral hypothalamus and showed that disconnection of that system abolished CPF. Then we showed that lateral hypothalamus orexin-producing neurons project to the mPFC. Finally, we blocked orexin receptor 1 signaling in the mPFC and showed that it is a neuromodulator necessary for the cue-driven consumption. Together, our findings identify a causal function for the mPFC in the cognitive motivation to eat.SIGNIFICANCE STATEMENTObesity has reached epidemic proportions, and the associated health consequences are serious and costly. The causes of obesity are complex because, in addition to physiological energy and nutrient needs, environmental cues can drive feeding through hedonic and cognitive processes. Learned food cues from the environment can powerfully stimulate appetite and food consumption in the absence of hunger. Using an animal model for cue-potentiated feeding, the current study determined the mPFC neuronal plasticity and neuropeptide orexin signaling are critical circuit and neurotransmitter mechanisms involved in this form of cognitive motivation to eat. These findings identify key targets for potential treatment of excessive appetite and overeating.

Mulheres de corpo e alga, cooperativa criada na comunidade da Barrinha, Icapuí-CE utiliza algas marinhas criando produtos, gerando renda e resíduos. O objetivo é identificar os teores de proteínas totais (PT), de carboidratos solúveis totais (AST), umidade e cinzas nos resíduos, antes e depois da adição de diferentes concentrações de S. cerevisiae, em diferentes tempos de exposição, buscando o tempo de fermentação adequado para melhorar a composição nutricional. Foi dividido em duas etapas: levedura nas concentrações de 0%, 5%. 10% e 15% e expondo em estufa à 36°C nos tempos de 0h, 24h, 48h e 72h. A estatística foi feita usando o software Assistat®, montado em experimento fatorial, com três repetições. Observou-se que o melhor tempo para aumento de PT foi 24h na concentração de 10% (C2). Na segunda etapa, ao tempo e a concentração ideal da primeira etapa foi adicionado três tipos de fonte de nitrogênio: Sulfato de amônio 2,5%, a Uréia a 2,5%; e Sulfato de amônio e Uréia (1,25%, cada) e, após a FSS foram feitos testes de PT, AST, umidade e cinzas. A suplementação com uréia apresentou maior PT possível devido a uma maior disponibilidade de nitrogênio para formação de proteínas, comportamento parecido com os AST. A umidade mais adequada a legislação foi a amostra C3 atribuida a biomassa microbiana e as cinzas não apresentaram diferença significativa possivelmente devido ao consumo de AST e compostos nitrogenados para fabricação das proteínas. O resíduo, sendo mais estudado, pode servir como uma alternativa para o produtor rural, como ração animal.
ANÁLISE DENDROCRONOLÓGICA DO CRESCIMENTO DE Araucaria angustifolia (Bertol.) Kuntze NO PLANALTO SERRANO DE SANTA CATARINA
Authors: Magalhães Loiola Táscilla 
Published: January 2020

Existe uma preocupação com a preservação do genótipo florestal das formações com a presença de Araucaria angustifolia (Bertol.) Kuntze, sendo necessária a aquisição de informações, como dados sobre o crescimento, incremento e idade das árvores, que possam ser utilizadas em planos de manejo sustentável. Assim, o objetivo deste estudo foi realizar um diagnóstico dendrocronológico do crescimento diamétrico acumulado para a compreensão da sua variabilidade, com a intenção de auxiliar nas ações de manejo da espécie. Para tanto, a partir da análise dos anéis de crescimento, foram utilizadas informações dendrocronológicas de 133 árvores, abordadas de maneira individual em fragmentos naturais, localizados no município de São Joaquim. Os resultados demonstraram que, nesses fragmentos, a espécie apresenta incremento em diâmetro variando entre 0,20 e 1,42 cm.ano-1, e idade variando de 16 a mais de 100 anos. Nos sítios estudados, ocorre uma redução gradativa do crescimento em diâmetro com aumento da idade, elucidando uma perda na capacidade de crescimento da espécie e a necessidade de intervenções com manejo sustentável.
