Objective:To evaluate the application of a fabricated dressing containing kaolin for skin regeneration in a rat model of excisional wounds.Method:In the present study, kaolin was loaded into electrospun polyvinyl alcohol (PVA)/chitosan polymer blend to develop a composite nanofibrous dressing. To make the yarns, kaolin with weight ratio of 5% was added to PVA/chitosan polymer blend and subsequently formed into nanofibres using the electrospinning method. Scaffolds were evaluated for to their microstructure, mechanical properties, surface wettability, water vapour transmission rate, water-uptake capacity, blood uptake capacity, blood compatibility, microbial penetration test, the number of colonies, and cellular response with the L929 cell line. Rats with full-thickness excisional wounds were treated with kaolin-containing and kaolin-free dressings.Results:The study showed that rats treated with the kaolin-incorporated mats demonstrated a significant closure to nearly 97.62±4.81% after 14 days compared with PVA/chitosan and the sterile gauze, which showed 86.15±8.11% and 78.50±4.22% of wound closure, respectively. The histopathological studies showed that in the PVA/chitosan/kaolin group, dense and regular collagen fibres were formed, while wounds treated with sterile gauze or PVA/chitosan scaffolds had random and loose collagen fibres.Conclusion:Our results show the potential applicability of PVA/chitosan/kaolin scaffolds as a wound care material.
Consideration of temperature-dependent emissivity of selective emitters in thermophotovoltaic systems
Authors: Bhatt Rajendra , Kravchenko Ivan , Gupta Mool 
Published: May 2020

Spectral emissivity control is paramount for designing a high-efficiency selective emitter surface required for thermophotovoltaic (TPV) applications. Owing to the temperature dependency of materials optical constants, the spectral properties of a selective emitter surface changes with the emitter temperature. This paper presents the fabrication of a multilayer metal-dielectric (

Characterizing the spatiotemporal envelope of the human visual system through the visibility of temporal aliasing artifacts
Authors: Mackin Alex , Bull David 
Published: May 2020

Previous studies have demonstrated that the onset of temporal aliasing artifacts occurs when the spatial displacement between samples reaches a critical distance, and that subsequently a linear relationship exists between stimulus speed and critical sampling rates. In this paper, we carry out further experimentation using a novel experimental setup, in which a strobe light is used to emulate impulsive temporal sampling, in order to investigate the spatiotemporal envelope of the human visual system and the effect of a stimulus. For non-periodic stimuli, experimental results show that critical sampling rates increase with motion speed and decrease with stimulus width. These interactions can be described using simple log-linear models, and characterized using the temporal aliasing visibility function, where maximum critical frame rates up to 1500 Hz are predicted. For periodic stimuli, we demonstrate that both perceptible temporal aliasing artifacts and stimulus aliasing can cause stroboscopic effects.
A compact high-precision periodic-error-free heterodyne interferometer
Authors: Joo Ki-Nam , Clark Erin , Zhang Yanqi , Ellis Jonathan D. , Guzmán Felipe 
Published: May 2020

We present the design, bench-top setup, and experimental results of a
compact heterodyne interferometer that achieves picometer-level
displacement sensitivities in air over frequencies above 100 MHz. The
optical configuration with spatially separated beams prevents
frequency and polarization mixing, and therefore eliminates periodic
errors. The interferometer is designed to maximize common-mode optical
laser beam paths to obtain high rejection of environmental
disturbances, such as temperature fluctuations and acoustics. The
results of our experiments demonstrate the short- and long-term
stabilities of the system during stationary and dynamic measurements.
In addition, we provide measurements that compare our interferometer
prototype with a commercial system, verifying our higher sensitivity
of 3 pm, higher thermal stability by a factor of two, and
periodic-error-free performance.

Banach, M.A. Michalski, J. Sójka, „Człowiek i Społeczeństwo” vol. XLVI: Między Chinami a Zachodem. Pytanie o źródła chińskiego sukcesu gospodarczego [Between China and the West. An inquiry into the sources of the Chinese economic miracle], Poznań 2018, pp. 85–102, Adam Mickiewicz University. Faculty of Social Sciences Press. ISSN 0239-3271
The study of Chinese culture and its influence on economy is not an easy task due to the size of this country, its multiculturalism, economic differences between regions, differences in the types of business ownership and cultural differences of generations of the inhabitants of the Middle Kingdom. Research by G. Hofstede, R. Gesteland or the concepts of F. Fukuyama and other researchers can be a good and reliable starting point for in-depth further research. Relying on them only, however, can lead to a certain schematic in the perception of this country. The rebirth of traditional religions of this country and their specific syncretism may have a significant impact on the business conducted in China.
An Archive in a Book: Documents and Letters from the Early-Mamluk Period
Authors: Liebrenz Boris 
Published: May 2020

Abstract
The nature and place of archives in the premodern Islamicate world is a much debated topic and various explanations are offered for the relative scarcity of preserved material as well as the regional imbalance in the record. One factor that stands out in this discussion is the general prominence of counter-archival practices for the survival of what we are studying today. This contribution is the first to examine one such practice that has led to the preservation of a great number of documents: the reuse of discarded papers for the production of bindings. The case study looks at the binding of Leiden Or. 122, which preserved letters, decrees, and lists from Egypt and Syria at the beginning of the Mamluk reign. They likely belonged to a large household in Cairo, more precisely located in the Ayyubid palace Iṣṭabl al-Quṭbiyya. The article offers an edition of the material with an analysis of the historical circumstances, namely the eventful early years of Mamluk rule in Egypt and Syria.

AbstractTwelve Sprague-Dawley rats were randomly divided into two groups: Citrus suavissima Hort. ex Tanaka group and control group (n = 6). The rats in Citrus suavissima Hort. ex Tanaka group were given Citrus suavissima Hort. ex Tanaka juices (1 mL/100 g) by oral administration each day, continued for 14 days; the rats in control group were given Stroke-physiological saline solution (1 mL/100 g) by oral administration each day, continued for 14 days. The rats of these two groups were given a single oral administration of erlotinib (20 mg/kg) on the 15th day. After blood sampling at different time points and processing, the concentrations of erlotinib in rat plasma were determined by the established ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method. Chromatographic separation was achieved using a UPLC BEH C18 column (2.1 mm × 50 mm, 1.7 μm) with erlotinib-d6 as an internal standard (IS). The initial mobile phase consisted of acetonitrile and water (containing 0.1% formic acid) with gradient elution. Multiple reaction monitoring (MRM) modes were utilized to conduct quantitative analysis. The sensitive, rapid and selective UPLC-MS/MS method was successfully applied to analyse the effect of Citrus suavissima Hort. ex Tanaka on pharmacokinetics of erlotinib in rat plasma. There were no significant differences in AUC(0−t), t1/2, Tmax, CL, Cmax between the two groups (P > 0.05). While MRT(0−t) was decreased (P < 0.05) in Citrus suavissima Hort. ex Tanaka group, compared to the control group. It showed that Citrus suavissima Hort. ex Tanaka could not affect the metabolism of erlotinib.

ANÁLISE PREDITIVA DE CASOS CONFIRMADOS DE COVID-19 NO BRASIL E EM OITO PAÍSES BASEADA NO MODELO NÃO LINEAR DE GOMPERTZ
Authors: Barros Kaio Diego das Neves 
Published: May 2020

Este estudo objetivou avaliar o avanço casos confirmados de Covid-19 no Brasil e em oito países (Áustria, China, Alemanha, Itália, Nova Zelândia Espanha, Reino Unido e Estados Unidos) através do modelo não linear de Gompertz. Os dados foram obtidos em relatórios oficias da Organização Mundial da Saúde (OMS) e foram submetidos à análise iterativa pelo método dos quadrados mínimos para estimação dos parâmetros , e através de procedimento NLIN (SAS versão 9.4). A aceleração absoluta foi obtida pelo log de base dos dados observados e a aceleração por dia pela derivada de terceira ordem do modelo preditivo. O coeficiente de correlação (R2) foi calculado por meio do procedimento CORR (SAS versão 9.4), assim como a correlação das assíntotas com a extensão da quarentena (dias) e com a densidade populacional de cada país. No momento, o modelo preditivo sugere que o Brasil está em curva ascendente de casos com tendência a alcançar 2.226.429 pessoas no total (R2=0,9984). A aceleração absoluta evidenciou aumento e a aceleração por dia demonstrou que apenas o Brasil está em movimento acelerado de casos e a tendência é que passe a diminuir somente a partir de 04/julho. As correlações sugerem que a eficácia da quarentena não está relacionada à sua extensão (dias), já que países com maior densidade populacional apresentaram diminuição de casos em menor tempo de restrição.
