Incorporation of silver stearate nanoparticles in methacrylate polymeric monoliths for hemeprotein isolation
Authors: Alzahrani Eman 
Published: May 2020

AbstractA unique method was used to synthesize extremely stable silver stearate nanoparticles (AgStNPs) incorporated in an organic-based monolith. The facile strategy was then used to selectively isolate hemeproteins, myoglobin (Myo) and hemoglobin (Hb). Ethyl alcohol, silver nitrate, and stearic acid were, respectively, utilized as reducing agents, silver precursors, and capping agents. The color changed to cloudy from transparent, indicating that AgStNPs had been formed. AgStNP nanostructures were then distinctly integrated into the natural polymeric scaffold. To characterize the AgStNP–methacrylate polymeric monolith and the silver nanoparticles, energy-dispersive X-ray (EDX), scanning electron microscopy (SEM), and Fourier-transform infrared (FT-IR) spectroscopy were used. The results of the SEM analysis indicated that the AgStNP–methacrylate polymeric monolith’s texture was so rough in comparison with that of the methacrylate polymeric monolith, indicating that the extraction process of the monolith materials would be more efficient because of the extended surface area of the absorbent. The comparison between the FT-IR spectra of AgStNPs, the bare organic monolith, and AgStNP–methacrylate polymeric monolith confirms that the AgStNPs were immobilized on the surface of the organic monolith. The EDX profile of the built materials indicated an advanced peak of the Ag sequence which represented an Ag atom of 3.27%. The results therefore established that the AgStNPs had been successfully integrated into the monolithic materials. Extraction efficiencies of 92% and 97% were used to, respectively, recover preconcentrated Myo and Hb. An uncomplicated method is a unique approach of both fabrication and utilization of the nanosorbent to selectively isolate hemeproteins. The process can further be implemented by using other noble metals.
Investigation of structural performance subjected to impact loading using finite element approach: case of ship-container collision
Authors: Prabowo Aditya Rio , Laksono Fajar Budi , Sohn Jung Min 
Published: May 2020

Abstract
Transporting mass products from one country to others is essential activities in industrial cycle. Ships are selected as reliable carriers for this objective considering traveling time and operational cost. During its operational, accidental events such as storm, high tide and bad weather may cause the products which are usually packed in freight containers fall into sea, and impacts the ship structure. In this situation, casualties on both involved structures can be detrimental. This work analyzes a series of ship-container collision in maritime territory in order to investigate resulting structural phenomena. The finite element approach is selected to solve the designed collision cases where the discussion is directed to selected crash-worthiness criteria. Impact speed between ship and container structures is chosen as the main parameter in the designed scenario by judging whether this parameter is a good representative of sea state. Overall results indicate that the indication for container rebounding after impact was high. It was followed by a significant increment of the internal energy after higher velocity, which was more than 5 m·s−1, had been applied to the scenario. Quantification of specific structural performance suggests that approximately more than 80% of the damage occurrs on the contacted area of the container structure.
Characteristic feature analysis of continuous optimization problems based on Variability Map of objective function for optimization algorithm configuration
Authors: Agasiev Taleh 
Published: May 2020

AbstractAdvanced optimization algorithms with a variety of configurable parameters become increasingly difficult to apply effectively to solving optimization problems. Appropriate algorithm configuration becomes highly relevant, still remaining a computationally expensive operation. Development of machine learning methods allows to model and predict the efficiency of different solving strategies and algorithm configurations depending on properties of optimization problem to be solved. The paper suggests the Dependency Decomposition approach to reduce computational complexity of modeling the efficiency of optimization algorithm, also considering the amount of computational resources available for optimization problem solving. The approach requires development of explicit Exploratory Landscape Analysis methods to assess a variety of significant characteristic features of optimization problems. The results of feature assessment depend on the number of sample points analyzed and their location in the design space, on top of that some of methods require additional evaluations of objective function. The paper proposes new landscape analysis methods based on given points without the need of any additional objective function evaluations. An algorithm of building a so-called Full Variability Map is suggested based on informativeness criteria formulated for groups of sample points. The paper suggests Generalized Information Content method for analysis of Full Variability Map which allows to get accurate and stable estimations of objective function features. The Sectorization method of Variability Map analysis is proposed to assess characteristic features reflecting such properties of objective function that are critical for optimization algorithm efficiency. The resulting features are invariant to the scale of objective function gradients which positively affects the generalizing ability of problems classification algorithm. The procedure of the comparative study of effectiveness of landscape analysis algorithms is introduced. The results of computational experiments indicate reliability of applying the suggested landscape analysis methods to optimization problem characterization and classification.
To be Black, Queer and Radical: Centring the epistemology of Marielle Franco
Authors: Loureiro Gabriela Silva 
Published: May 2020

AbstractThe aim of this article is to pay tribute to Marielle Franco, a Brazilian LGBTQ+ Black activist from the favela who was brutally executed in March 14, 2018. Taking Marielle’s life and death as a case study, I will demonstrate how she embodied Black feminist theory and practice and how her execution can be better addressed by situating it within the context of spatialities of race and the necropolitical governance of Rio de Janeiro.

„Was jede Seele sucht und worumwillen sie alles tut“
Authors: Ferber Rafael 
Published: May 2020

Abstract
The article first (i) gives an exegesis of the famous passage in the Republic, 505d11-506a2. Attention is drawn to the fact that the principle that every soul does everything for the Good (panta prattei) can be translated in two ways: Every soul does everything for the sake of the Good, or goes to all lengths for the sake of the Good. Depending on the different translations, we have a different picture of the platonic Socrates in the Republic, an intellectualistic Socrates for whom pure irrational desires do not exist, or a Socrates who also accepts irrational desires. The article favours the first picture. Then it (ii) attempts to show that we can elucidate two dark points in the Socratic thesis that the Good is what every soul pursues and for which every soul does everything, with the help of Aquinas. Finally, the article (iii) outlines three substantive answers to the question ``What is the Good?'' - the henological, the perfectionist and the structuralist - and shows that these three answers lead into a trilemma. Instead of advancing a new answer, the article suggests an uncontroversial formal starting point for an answer to this question.
Aristotelian Reminiscences in Philo
Authors: Glucker John 
Published: May 2020

Abstract
The first part of this article deals with two cases of what seems to be Aristotelian reminiscences in the works of Philo of Alexandria. A passage in Quod deterius and a passage in De agricultura show close verbal reminiscences to two passages in Book i of Nicomachean Ethics; and a passage in De migratione Abrahami shows verbal reminiscences to two passages in Book ii. Since it appears from Book v of De finibus that Antiochus of Ascalon had already read at least parts of Nicomachean Ethics; and the first commentator on the Ethics, Aspasius, has clear references to some predecessors who had already read and discussed this work, I argue for the possibility that Philo also read the Nicomachean Ethics. The second part deals with an almost forgotten book review by Jacob Freudenthal, published in 1875, which argues that Philo was familiar with various parts of the Aristotelian corpus as we have it. I examine his detailed arguments and conclude that, with all due respect to a great scholar, they do not seem to prove his point.
Concezioni stoiche e idee platoniche
Authors: Bonazzi Mauro 
Published: May 2020

Abstract
Aim of this paper is to show how Middle Platonist philosophers adapted Stoic epistemology to their own Platonist metaphysics. More precisely the discussion focuses on the key notion of ennoia (conception).Middle Platonists argue against the hypothesis that conceptions have an empirical origin and claim that an ennoia is what remains of the pre-natal vision of the ideas. According to them, it is only through metaphysics that a theory of knowledge can adequately be grounded. The second part of the paper delves into the limits of such a claim. The possibility of getting a proper knowledge of the ideas raises a problem, for if the ennoiai are grounded on the ideas, but the ideas are not object of a proper knowledge, we run the risk of not having a proper criterion anymore. On these grounds, we would not be able to account for the process of knowledge.
Dalla tecnica all’etica: argomentazioni peirastiche in Lachete, Carmide, Ippia minore e Protagora
Authors: Venturelli Silvia 
Published: May 2020

Abstract
The analogy between virtue and crafts is the core of Socratic ethics, whose fundamental principle is that virtue is a kind of knowledge similar to technical skills. Moral knowledge, however, is on a superior level and is different from other crafts since it concerns the ends of human action. This article aims to show that the main purpose of Laches, Charmides, Lesser Hippias and Protagoras is to bring out this distinction. More specifically, all the four dialogues follow a similar pattern, i.e. they lead to the conclusion that virtue is moral knowledge by means of preliminary argumentations which consider the opposite view, supposing that it consists in technical knowledge. Thus we are shown the difficulties arising if we fail to distinguish moral knowledge, before the dialogue reaches its positive conclusion.
Anaxagorae Homoeomeria
Authors: Torrijos-Castrillejo David 
Published: May 2020

Abstract
Aristotle introduced in the history of the reception of Anaxagoras the term “homoiomerous”. This word refers to substances whose parts are similar to each other and to the whole. Although Aristotle’s explanations can be puzzling, the term “homoiomerous” may explain an authentic aspect of Anaxagoras’ doctrine reflected in the fragments of his work. Perhaps one should find a specific meaning for the term “homoiomerous” in Anaxagoras, somewhat different from the one present in Aristotle. This requires a review of the sense of the two terms involved in it: “homoios” and “moira”. In other words, the following questions should be answered: what realities are named parts and to what whole do they belong? On the other hand, which similarity do they have to each another and to the whole? The author concludes that the parts are “all things”, which resemble each other and the universe as a whole because, according to Anaxagoras, they are all composed of all things.
Insight on the effect of a piperonylic acid derivative on the
crystallization process, melting behavior, thermal stability, optical and mechanical
properties of poly(l-lactic acid)
Authors: Zhao Li-Sha , Cai Yan-Hua 
Published: May 2020

Abstract
A new piperonylic acid derivative (BPASD) was synthesized and evaluated as an organic
nucleating agent for poly(l-lactic acid) (PLLA) via melt-crystallization;
the other behaviors including cold-crystallization, melting process after
crystallization, thermal stability in air atmosphere, and optical and mechanical
properties of PLLA/BPASD samples were also investigated. The results of the
melt-crystallization investigation showed that, in comparison to virgin PLLA, the
BPASD could induce PLLA to crystallize in higher temperature region or at a faster
cooling rate, suggesting that the BPASD as a heterogeneous nucleating agent could
promote the crystallization of PLLA, but the melt-crystallization depended on the
cooling rate, BPASD concentration, and the final melting temperature. With increasing
of BPASD concentration, a shift to the lower temperature of cold-crystallization peak
and decrease of crystallization enthalpy indicated that BPASD had an inhibition for
the cold-crystallization of PLLA to some extent. The heating rate, crystallization
temperature, the BPASD, and its concentration were critical factors to the melting
process, and double-melting peaks appeared in heating were assigned to
melting–recrystallization. Thermal decomposition behavior revealed that the
addition of BPASD reduced the thermal stability of PLLA, but the interaction of PLLA
and BPASD could prevent the decrease of the onset decomposition temperature. Further,
the BPASD also decreased the light transmittance and elongation at the break of PLLA,
but the tensile modulus and tensile strength of PLLA were enhanced.

The Crisis of Becoming-Nature in Howard Barker’s Recent Dramas
Authors: Gritzner Karoline 
Published: May 2020

AbstractThis article discusses how in Howard Barker’s recent work the idea of the subject’s crisis hinges on the introduction of an impersonal or transpersonal life force that persists beyond human agency. The article considers Barker’s metaphorical treatment of the images of land and stone and their interrelationship with the human body, where the notion of subjective crisis results from an awareness of objective forces that transcend the self. In “Immense Kiss” (2018) and “Critique of Pure Feeling” (2018), the idea of crisis, whilst still dominant, seems to lose its intermittent character of singular rupture and reveals itself as a permanent force of dissolution and reification. In these plays, the evocation of nonhuman nature in the love relationships between young men and elderly women affirms the existence of something that goes beyond the individual, which Barker approaches with a late-style poetic sensibility.
Fifteen-Minute Moments: Black Women’s Short Plays as a Political Aesthetic of Crisis
Authors: Goddard Lynette 
Published: May 2020

AbstractThis article examines short plays as a political aesthetic of crisis using examples from Black Lives, Black Words (2015–2017) at the Bush Theatre, London, which respond to concerns arising from the #BlackLivesMatter movement about Black deaths in police custody. I focus on Black women playwrights’ portrayals of Black mothers’ anxieties about protecting their sons, and of Black mothers and sisters grieving the loss of sons, brothers, and fathers in incidents where excessive force is deployed by the police. I consider how Black Lives, Black Words connects to the radical aesthetics of the 1960 s Black Arts Movement by promoting the use of theatre for activist purposes. I argue that the politicising potential of the Black Lives, Black Words initiative is accentuated by the use of a short play format as a political Black aesthetics for responding to contemporary crises. By analysing pivotal moments in a sample of the fifteen-minute plays, I demonstrate how the content of the plays combines with their performance styles to maximise the potential for audience empathy despite their short playing times.

A hybrid air-sea cooperative approach combined with a swarm trajectory planning method
Authors: Bella Salima , Belbachir Assia , Belalem Ghalem 
Published: May 2020

AbstractThis work addresses the issue of ocean monitoring and clean-up of polluted zones, as well as the notion of trajectory planning and fault tolerance for semi-autonomous unmanned vehicles. A hybrid approach for unmanned aerial vehicles (UAVs) is introduced to monitor the ocean region and cooperate with swarm of unmanned surface vehicles (USVs) to clean dirty zones. The paper proposes two solutions that apply to trajectory planning from the base of life to the dirty zone for swarm USVs. The first solution is performed by a modified Genetic Algorithm (GA), and the second uses a modified Ant Algorithm (AA). The proposed solutions were both implemented in the simulation with different scenarios for the dirty zone. This approach detects and reduces the pollution level in ocean zones while taking into account the problem of fault tolerance related to unmanned cleaning vehicles.
Opportunities for modelling inflation processes in Lithuania
Authors: Čuvak Ana , Kalinauskas Žilvinas 
Published: May 2020

Inflation is a constant and consistent increase in the general price level in the country, due to which the purchasing power of a national currency unit decreases. In practice, the measures of inflation are various price indices, such as a consumer price index (CPI), producer price index (PPI), or gross domestic product deflator. However, inflation is usually defined as a change in the HCPI over a year. Time series models, linear regression models and a vector autoregression model (VAR) can be used to model and forecast inflation processes. This paper examines Lithuanian consumer price inflation using a modern stationary time series and econometric theory. The vector autoregression model is proposed for inflation modelling. Theoretical aspects of model estimation are reviewed: time series stationarity, model identification, parameter estimation, model usage and forecasts. The stationarity of the HCPI index and exogenous variables are analyzed using the Augmented Dickey–Fuller (ADF) test. A vector autoregression model of Lithuanian inflation processes is investigated and proposed for inflation modelling. The obtained model is used for forecasting purposes and shows a fairly high degree of accuracy of the inflation forecast in the coming 12-month period.
Proximate and starch composition of marama (Tylosema esculentum) storage roots during an annual growth period
Authors: Hamunyela Maria H. , Nepolo Emmanuel , Emmambux Mohammad N. 
Published: May 2020

The aim of this study was to determine the most suitable time for harvesting marama (Tylosema esculentum) root as an alternative source of novel starch by evaluating the quality of marama root and its starch during growth periods of 12 months. The effects of time on the proximate analysis of marama roots as well as the thermal properties, size and physicochemical properties of the starch were also investigated. Marama was planted in September and total starch of marama roots on both as is and dry bases increased significantly (p<0.05) from 24 g/kg to 115 g/kg and 259 g/kg to 601 g/kg, respectively, from 2 to 12 months after planting. Amylose content significantly (p<0.05) decreased from about 50.7% to 21.4% of the starch for the same time period. The size of marama root starch granules significantly (p<0.05) increased from 8.6 μm to 15.1 μm. The marama root harvested after 2 months had the highest crude protein content (33.6%). In terms of thermal properties, the peak temperature decreased significantly with time (ranging from 93.0 °C to 73.4 °C), while the ΔH increased significantly with time. The findings indicate that marama should be planted early in summer and harvested between 4 and 8 months for optimal starch before winter.
Significance:

Proximate and starch characteristics of marama storage roots differ significantly with time of harvest. This suggests that desired functional properties can be achieved by controlling growth time. The marama root harvested at 4 months is highly nutritious, it has high protein content, starch that is high in amylose and is suitable for consumption as a fresh root vegetable in arid to semi-arid regions where few conventional crops are able to survive. Marama root is a climate smart crop and it could potentially contribute to food security in arid regions. The results obtained in this study suggest that the optimum time for harvesting marama as a root vegetable is at 4 months while the optimum time for harvesting marama for its starch is at 8 months. Younger roots have higher amylose, and hence higher gelatinisation temperatures, and therefore may be more suitable to be used as a coating during frying.
