Trans Pornography
Authors: Pezzutto Sophie , Comella Lynn 
Published: May 2020

AbstractThis article introduces the field of trans pornography studies and makes a case for why studying it matters. We locate trans pornography within the broader field of porn studies, while also pointing to its importance to transgender studies. We map the history of trans pornography and examine the wider social, political, and economic forces contributing to the transformation of trans porn into a genre of mainstream straight porn. We discuss the economic organization of the trans porn industry and current industry trends, including geographical shifts in production and the rise of alternative production platforms. We address areas of future research and the need for more scholarship on the political economy of the trans porn industry, audiences and consumers, transmasculine representation in pornography, and research that focuses on trans porn production outside the United States.
Ajita Wilson
Authors: Richardson Matt 
Published: May 2020

Abstract
This article puts forward a consideration of Black womanhood by looking at the softcore films starring African American trans model and actress, Ajita Wilson. Wilson starred in many European softcore and hardcore films from the 1970s until her death in 1987. The author is particularly interested in Wilson's 1976 film The Nude Princess and the 1977 film Black Afrodite (Mavri Afroditi) for their use of soul aesthetics. Conceptualized in dialogue with Tanisha Ford's discussion of “soul style,” soul aesthetics are a combination of gestures as well as visual and auditory references in dress, music, literature, and language that were generated by Black people during a period of African and Caribbean anticolonialism and liberatory Black civil rights movements. Because they were born from radical movement politics, these references have transnationally come to symbolize the possibility for Black collective and self-transformation. The author offers an analysis of these films as an example of softcore pornography affirming Black womanhood and focuses on what this process of self-making has to offer Black trans and queer feminist thought.

Effect of olive oil administration on the level of transforming growth factor β1 during orthodontic tooth movement in old and young guinea pigs
Authors: Suparwitri Sri , Noviasari Paramita 
Published: May 2020

Background: Orthodontic tooth movement occurs due to continuous pressure on the teeth, causing the remodeling of the alveolar bone. The tissue will respond to bone growth factors, such as transforming growth factor β1 (TGF-β1), fibroblasts, and bone morphogenetic proteins, for new bone formation. The remodeling process is balanced in young adults, but there is an imbalance in older individuals due to decreased differentiation, activity, and life span of osteoblasts, and increased osteoclasts. Olive oil contains lots of antioxidants and can slow down the aging process. This study aims to study the differences in TGF-β1 levels between old and young guinea pigs, and the difference between olive oil administration on TGF-β1 levels in old and young guinea pigs with orthodontic tooth movement. Methods: 12 guinea pigs divided into 4 groups: young guinea pigs (4-5 months) not given olive oil; young guinea pigs given olive oil; old guinea pigs (30-31 months) given olive oil; old guinea pigs given olive oil. The teeth were moved using an open coil spring mounted on the brackets on both lower incisors. Gingival sulcus fluid samples were taken on days 0, 7 and 14 of the movement of the teeth. TGF-β1 levels were analyzed using ELISA. Results: Three-way ANOVA and post hoc statistical tests showed that TGF-β1 levels in young guinea pigs were significantly higher than old guinea pigs on days 0, 7 and 14 (p<0.05). TGF-β1 levels in both young and old guinea pigs who were given olive oil was significantly higher than those not given olive oil on days 0, 7 and 14 (p<0.05). Conclusions: TGF-β1 levels in the younger age guinea pigs were higher than the older age, and olive oil could increase TGF-β1 levels in the older age guinea pigs.

Published: May 2020

Background: Moral Growth Mindset (MGM) is a belief about whether one can become a morally better person through efforts. Prior research showed that MGM is positively associated with promotion of moral motivation among adolescents and young adults. We developed and tested the English version of the MGM measure in this study with data collected from college student participants. Methods: In Study 1, we tested the reliability and validity of the MGM measure with two-wave data (N = 212, Age mean = 24.18 years, SD = 7.82 years). In Study 2, we retested the construct validity of the MGM measure once again and its association with other moral and positive psychological indicators to test its convergent and discriminant validity (N = 275, Age mean = 22.02 years, SD = 6.34 years). Results: We found that the MGM measure was reliable and valid from Study 1. In Study 2, the results indicated that the MGM was well correlated with other moral and positive psychological indicators as expected. Conclusions: We developed and validated the English version of the MGM measure in the present study. The results from studies 1 and 2 supported the reliability and validity of the MGM measure. Given this, we found that the English version of the MGM measure can measure one’s MGM as we intended.
Pre-diabetes and cardiovascular risk: detonating the time bomb
Authors: Bostock-Cox Beverley 
Published: May 2020

Pre-diabetes carries a cardiovascular risk. Beverley Bostock-Cox considers the interventions that can improve this risk in people with pre-diabetes Pre-diabetes is a state of impaired glucose regulation where the body moves from normal levels of blood glucose to a position where increasing levels of insulin resistance result in higher and harmful sugar levels in the bloodstream. As its name suggests, it is a precursor of type 2 diabetes. Cardiovascular risk is also likely to be higher, mainly because of the links between hyperglycaemia and other known cardiovascular risk factors such as hypertension and dyslipidaemia. In people with pre-diabetes, the aim should be to treat all the modifiable risk factors through lifestyle interventions, especially by encouraging weight loss and increasing physical activity levels. Pharmacological interventions can be considered in addition to lifestyle change.

Abstract. Pazla R, Jamarun N, Agustin F, Zain M, Cahyani NO. 2020. Effects of supplementation with phosphorus, calcium and manganese during oil palm frond fermentation by Phanerochaete chrysosporium on ligninase enzyme activity. Biodiversitas 21: 1833-1838. The objective of this study was to evaluate the effects of supplementation with phosphorus (P) in combination with calcium (Ca) and manganese (Mn) during oil palm frond (OPF) fermentation by Phanerochaete chrysosporium on ligninase enzyme activity and lignin degradation. This study was carried out using a randomized complete design with 3 treatments (addition of P, Ca and Mn) and 5 replicates. The following treatments were performed: T1 (P 1000 + Ca 2000 + Mn 150 ppm), T2 (P 1500 + Ca 2000 + Mn 150 ppm), and T3 (P 2000 + Ca 2000 +Mn 150 ppm). The data were subjected to an analysis of variance (ANOVA), and differences between treatment means were tested using Duncan's multiple range test (DMRT). The parameters measured were as follows: lignin peroxidase (LiP) activity (U/mL), manganese peroxidase (MnP) activity (U/mL), crude protein (CP) content (%), crude fiber (CF) content (%) and the decrease in lignin (%). The results revealed a significant increase in LiP activity and CP content and a decrease in the lignin content (p<0.05) by the addition of P in the T3 treatment. However, the treatment nonsignificantly increased (p>0.05) MnP activity and significantly decreased (P<0.05) the CF content. In conclusion, supplementation of the OPF fermentation process with P 2000, Ca 2000, and Mn 150 ppm resulted in the highest ligninase enzyme activity and in decreased lignin content.
IUPAC Periodic Table Challenge

Published: May 2020

Abstract
In 2019, the world celebrated the International Year of the Periodic Table of Chemical Elements (IYPT2019) and the IUPAC centenary. This happy coincidence offered a unique opportunity to reflect on the value and work that is carried out by IUPAC in a range of activities, including chemistry awareness, appreciation, and education. Although IUPAC curates the Periodic Table and oversees regular additions and changes, this icon of science belongs to the world. With this in mind, we wanted to create an opportunity for students and the general public to participate in this global celebration. The objective was to create an online global competition centered on the Periodic Table and IUPAC to raise awareness of the importance of chemistry in our daily lives, the richness of the chemical elements, and the key role of IUPAC in promoting chemistry worldwide. The Periodic Table Challenge was the result of this effort.
Two new forms of ordered soft separation axioms
Authors: Al-shami Tareq M. , El-Shafei Mohammed E. 
Published: May 2020

AbstractThe goal of this work is to introduce and study two new types of ordered soft separation axioms, namely soft Ti-ordered and strong soft Ti-ordered spaces (i = 0, 1, 2, 3, 4). These two types are formulated with respect to the ordinary points and the distinction between them is attributed to the nature of the monotone neighborhoods. We provide several examples to elucidate the relationships among these concepts and to show the relationships associate them with their parametric topological ordered spaces and p-soft Ti-ordered spaces. Some open problems on the relationships between strong soft Ti-ordered and soft Ti-ordered spaces (i = 2, 3, 4) are posed. Also, we prove some significant results which associate both types of the introduced ordered axioms with some notions such as finite product soft spaces, soft topological and soft hereditary properties. Furthermore, we describe the shape of increasing (decreasing) soft closed and open subsets of soft regularly ordered spaces; and demonstrate that a condition of strong soft regularly ordered is sufficient for the equivalence between p-soft T1-ordered and strong soft T1-ordered spaces. Finally, we establish a number of findings that associate soft compactness with some ordered soft separation axioms initiated in this work.
S100A6 promotes proliferation and migration of HepG2 cells via increased
ubiquitin-dependent degradation of p53
Authors: Song Dongqiang , Xu Beili , Shi Dongmin , Li Shuyu , Cai Yu 
Published: May 2020

Abstract

Purpose
S100A6 protein (calcyclin), a small calcium-binding protein of the S100 family, is
often upregulated in various types of cancers, including hepatocellular carcinoma
(HCC). The aim of this study was to illustrate the molecular mechanism of S100A6
in regulating the proliferation and migration of HCC cells.

Methods
The expressions of S100A6 in human HCC and adjacent non-tumor liver specimens were
detected using immunoblotting and quantitative PCR (qPCR). The recombinant
glutathione S-transferase (GST)-tagged human S100A6 protein was purified and
identified. After treatment with S100A6, the proliferation of HepG2 cells was
detected by the MTT and colony formation assay, and the migration of HepG2 cells
was investigated by the transwell migration assay; the protein levels of cyclin D1
(CCND1), E-cadherin, and vimentin were also tested by immunoblotting. The effect
of S100A6 on p21 and nuclear factor-κB pathway was verified by performing
the dual luciferase assay. Then, the expression of p21 and its transcription
activator, p53, was examined using immunoblotting and qPCR, the ubiquitination of
which was investigated through co-immunoprecipitation.

Results
It was found that the level of S100A6 was higher in the HCC tissues than in the
adjacent non-tumor liver specimens. Exogenous overexpression of S100A6 promoted
the proliferation and migration of HepG2 cells. S100A6 was observed to regulate
p21 mRNA and protein expression levels and decrease p53 protein expression level,
not mRNA level, by promoting the ubiquitination of p53 via the
proteasome-dependent degradation pathway.

Conclusion
Our study indicated that S100A6 overexpression could promote the proliferation and
migration of HCC cells by enhancing p53 ubiquitin-dependent proteasome
degradation, ultimately regulating the p21 expression level.

Published: May 2020

Abstract
Recently, sonochemistry has been used for the synthesis of inorganic compounds, such as zinc borates. In this study using zinc sulphate heptahydrate (ZnSO4·7H2O) and boric acid (H3BO3) as starting materials, a zinc borate compound in the form of Zn3B6O12·3.5H2O was synthesized using an ultrasonic probe. Product’s characterization was carried out with using X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR) and Raman spectroscopy. Zinc borate compound’s chemical bond structure was observed with Raman and FTIR. From the XRD results it was seen that Zn3B6O12·3.5H2O can be quickly synthesized upon heating at 80°C and 85°C (55 min) or 90°C (45 min) in very high yield (>90%). The minimum particle size obtained was ~143 μm from the SEM results. Zinc borate compound was synthesized at a lower temperature in less time than other synthesized zinc metal compound in literature.

Abstract
Information regarding the interaction between biological nitrogen fixation (BNF) with Azospirillum brasilense inoculation and the use of silicon (Si) is needed. Silicon exerts numerous benefits on grasses, especially when the plants are subjected to biotic and abiotic stresses, affecting plant nutrition. The aim of this research was to determine if there is a synergistic effect between the inoculation with A. brasilense and Si use, on macro-nutrient content in corn shoot and root. The field trial was performed in Selvíria, Brazil, on a Typic Rhodic Hapludox soil under no-till system. The experimental design was a completely randomized block design with four replicates arranged in a 2 × 5 × 2 triple factorial arrangement, consisting of two soil acidity corrective sources (dolomitic limestone and Ca and Mg silicate as sources of Si); five N doses (0, 50, 100, 150 and 200 kg ha-1 applied in topdressing); with and without seed inoculation with A. brasilense. The inoculation favored N concentration in shoots and increased the N and S concentration even when associated to high N rates in topdressing. The Si as Ca and Mg silicate associated with the increment of N rates does not promote an increase in the macronutrients uptake. Although it did not favor the N use, the Si also did not negatively affect the benefits of the A. brasilense.
Living and Nonliving Occasionalism
Authors: Weir Simon 
Published: May 2020

AbstractGraham Harman’s Object-Oriented Ontology has employed a variant of occasionalist causation since 2002, with sensual objects acting as the mediators of causation between real objects. While the mechanism for living beings creating sensual objects is clear, how nonliving objects generate sensual objects is not. This essay sets out an interpretation of occasionalism where the mediating agency of nonliving contact is the virtual particles of nominally empty space. Since living, conscious, real objects need to hold sensual objects as sub-components, but nonliving objects do not, this leads to an explanation of why consciousness, in Object-Oriented Ontology, might be described as doubly withdrawn: a sensual sub-component of a withdrawn real object.

Published: May 2020

AbstractA dielectric barrier discharge plasma controlled diffusion flame experimental system was built based on the designed coaxial swirling plasma injector. The air plasma was generated within the annulus gap of the injector by alternating current dielectric barrier discharge. The discharge characteristics and power of plasma injector under different actuation intensities and air flowrates were measured. Through the measurement techniques, such as schlieren imaging, broadband chemiluminescence image and CH* chemiluminescence, the effect and mechanism of plasma on ethylene-air normal diffusive jet and flame was explored. The results showed that a large number of filamentary discharge channels are formed in air plasma. The increase of air flowrates weakened the intensity of discharge to a certain extent. The induced jet generated by the plasma can short the laminar length of the ethylene-air jet, accelerate the transition of the flow jet, enhance the turbulence and the mixing of the fuel and the oxidizer. The higher the actuation intensity, the shorter distance of the cold jet transition zone, the higher the jet turbulence. Depending on the aerodynamic and kinetic effects, plasma can improve the stability of ethylene-air diffusive flame and reduce the lift height between the flame root and injector. The plasma can also expand the flammability limit of ethylene-air flame and make the flame ignited under some conditions that could not be. In addition, the CH* chemiluminescence shows that, in a certain range of discharge voltage, the heat release distribution can be changed on both sides of the flame, and its representative length are generally reduced as the voltage rises. On the contrary, the overtop voltage could lead to a decrease of flame heat release.
On the spectrum of noisy blown-up matrices
Authors: Fazekas István , Pecsora Sándor 
Published: May 2020

AbstractWe study the eigenvalues of large perturbed matrices. We consider a pattern matrix P, we blow it up to get a large block-matrix Bn. We can observe only a noisy version of matrix Bn. So we add a random noise Wn to obtain the perturbed matrix An = Bn + Wn. Our aim is to find the structural eigenvalues of An. We prove asymptotic theorems on this problem and also suggest a graphical method to distinguish the structural and the non-structural eigenvalues of An.

Noise is a stressor for hearing loss among workers. Unfortunately, hearing loss also affect worker’s quality of life. This study aimed to investigate the correlation between hearing loss and quality of life among workers in textile industry. The study design was a cross-sectional survey. The study population were 200 workers exposed to the noisy textile industry. The data were analyzed using Spearman's rank correlation coefficient. The findings showed a significant relationship between hearing loss and the quality of life of the workers (rs=-0.698; p=0.000). The dimensions of quality of life associated with hearing loss were the Physical Functioning (rs=-0.493; p=0.000), Role-Physical (rs=-0.501; p=0.000), Bodily Pain (rs=-0.516; p=0.000), General Health (rs=-0.497; p=0.000), Vitality (rs=-0.527; p=0.000), Social Functioning (rs=-0.521; p=0.000), Role-Emotional (rs=-0.521; p=0.000), and Mental Health (rs=-0.517; p=0.000). This study concludes that hearing loss decreases the quality of life among workers exposed to the noise of the textile industry.
