BackgroundPatients suffering from severe trauma experience substantial immunological stress. Lung injury is a known risk factor for the development of posttraumatic complications, but information on the long-term course of the pulmonary inflammatory response and treatment with mild hypothermia are scarce.AimTo investigate the pulmonary inflammatory response to multiple trauma and hemorrhagic shock in a porcine model of combined trauma and to assess the immunomodulatory properties of mild hypothermia.MethodsFollowing induction of trauma (blunt chest trauma, liver laceration, tibia fracture), two degrees of hemorrhagic shock (45 and 50%) over 90 (n = 30) and 120 min. (n = 20) were induced. Animals were randomized to hypothermia (33°C) or normothermia (38°C). We evaluated bronchoalveolar lavage (BAL) fluid and tissue levels of cytokines and investigated changes in microRNA- and gene-expression as well as tissue apoptosis.ResultsWe observed a significant induction of Interleukin (IL) 1β, IL-6, IL-8, and Cyclooxygenase-2 mRNA in lung tissue. Likewise, an increased IL-6 protein concentration could be detected in BAL-fluid, with a slight decrease of IL-6 protein in animals treated with hypothermia. Lower IL-10 protein levels in normothermia and higher IL-10 protein concentrations in hypothermia accompanied this trend. Tissue apoptosis increased after trauma. However, intervention with hypothermia did not result in a meaningful reduction of pro-inflammatory biomarkers or tissue apoptosis.ConclusionWe observed signs of a time-dependent pulmonary inflammation and apoptosis at the site of severe trauma, and to a lower extent in the trauma-distant lung. Intervention with mild hypothermia had no considerable effect during 48 hours following trauma.

Este texto faz uma reflexão dos levantes mobilizados pela Arte Indígena Contemporânea, mais especificamente aqueles enredados pelas giras e voltas que o manto tupinambá tem desenhado no diagrama da dita arte contemporânea brasileira. A partir das exposições Um outro céu (2020) e Kwá Yepé Turusú Yuriri Assojaba Tupinambá - Essa é a grande volta do manto tupinambá (2021), ambas agregadas em torno do trabalho de Glicéria Tupinambá e na ativação “Ativação Morî' erenkato eseru' - Cantos para a vida”, realizada por Daiara Tukano e Jaider Esbell, na exposição Véxoa: nós sabemos (2020), o Levante dos mantos reúne um conjunto de confrontos éticos-estéticos e políticos ante a autoridade e a naturalização do espúrio e dos saqueamentos coloniais, na expectativa de fazer ressoar as incessantes disputas de narrativas no campo das artes, com protagonismo do movimento autodeclarado como Arte Indígena Contemporânea (ESBELL, 2020).
LA GESTION DE LA DIVERSITE CULTURELLE PAR LES CHEFS D'ETABLISSEMENT REVUE DE LA LITTERATURE
Authors: Bauer Stéphanie , Akkari Abdeljalil 
Published: December 2022

Contemporary education systems need to address increasing Cultural diversity of students and the need to a change of perspective. From a problem to solve, cultural diversity can become an opportunity to improve learning. This article presents a synthesis of literature on the role of school principals in the management of cultural diversity. The academic literatureÂ Â on this issue is very heterogeneous. We present the main theoretical and conceptual debates. The notion of social justice appears to representÂ Â an innovative concept likely to destabilize unequal power relations between groups. The text discusses the professionalization of principals. This article highlights a tension between two visions of school leadership in the management of cultural diversity: a vision linked to critical pedagogy that develops multicultural education as a means to promote social justice and transformation of school structures. On the other side, an approach centered on management of education with a more focused approach towards measurable learning outcomesÂ Â and greater control of the cost of education.

Solvent effect, dipole moment, and DFT studies of multi donor–acceptor type pyridine derivative
Authors: Alarfaji Saleh S. , Al-Sehemi Abdullah G. , Pannipara Mehboobali 
Published: December 2022

Abstract
A donor–acceptor substituted derivative 2,6-diamino-4-(3,4,5-trimethoxy-phenyl)-pyridine-3,5-dicarbonitrile (DTPP) has been synthesized and its photophysical properties have been studied. Effect of solvent on the photophysical features of DTPP has been undertaken by steady state absorption and emission techniques. Strong solvatochromic emission has been observed due to intramolecular charge transfer characteristics, upon changing the solvent polarity, revealing the highly polar character of the excited state. Dipole moment changes between the excited and ground state have been estimated by using the theory of solvatochromism from Lippert–Mataga and Reichardt’s correlations. The geometrical parameters for ground and excited states, conformational flexibility, and NLO behavior of the molecule have been theoretically investigated. The electronic distributions of DTPP in HOMO and LUMO were also investigated using density functional theory (DFT) methods at B3LYP/6-31 G** level. The correlation of experimental results with theoretical predictions obtained via DFT substantiates the presence of polarity dependent of the emission spectra.

Published: December 2022

Abstract
The microstructure, mechanical properties and corrosion resistance of friction stir welded joint of Al–Mg–Mn–Zr–Er alloy were investigated under three FSW parameter sets: 800 rpm × 100 mm min−1, 800 rpm × 80 mm min−1 and 600 rpm × 80 mm min−1. The microstructural transformation sequence of welded joint is discontinuous dynamic recrystallization, dislocation introduction, dynamic recovery and continuous dynamic recrystallization. The mechanical properties of welded joint are highly correlated with the welding process parameters. The welded joint can obtain good tensile strength and elongation under the parameters of 800 rpm × 100 mm min−1. Corrosion resistance of welded joints has little correlation with welding parameters, but is mainly related to different positions of welded joints. The main influencing factor is grain structure state. The intergranular corrosion susceptibility is related to β(Al3Mg2) phase.

Published: December 2022

Abstract
Seafood is the food group with the highest share traded, and the U.S. is the world’s largest seafood importer, importing 79% of the seafood consumed. Hence, a study examining the impacts of the measures to contain COVID-19 on U.S. seafood imports will not only show how U.S. seafood availability has been affected, but will also give strong indications of how resiliently the global seafood markets have worked through the pandemic. We find that U.S. imports of seafood actually increased in 2020 and 2021, suggesting supply chains were able to adapt to potential disruptions. Moreover, for the 14 largest product forms imported to the U.S., there are no strong price movements. Given that there is a global market for most species groups, this adaption also suggests that the markets have worked quite well beyond the U.S. Hence, while there have undoubtedly been market shocks associated with the COVID-19 measures such as the reduction in demand from the restaurant sector and the increased sales in the retail sector, opportunities seem to balance out challenges, and the supply chains for seafood to the U.S. have been highly resilient.

Single fiber Bragg grating (FBG) power propagation, grating index change, coupling coefficient and apodization variations versus grating length variations is demonstrated at the central wavelength of 1550 nm by using both Hamming, Blackman impulse filter function and Hamming, Blackman grating profile. As well as the single FBG power spectrum, delay, dispersion, transmittivity/reflectivity are simulated and clarified against wavelength variations using both Hamming, Blackman impulse filter function and Hamming, Blackman grating profile. The Hamming impulse function filter and Hamming grating profile have clarified better performance than Blackman impulse function filter and Blackman grating profile.
A novel energy efficient routing technique for SDN-enabled underwater WSNs using free-space optical communication
Authors: Tyagi Vikas , Singh Samayveer 
Published: December 2022

Abstract
Free-space optical (FSO) wireless sensor network is rapidly growing for underwater communication applications. However, the high-energy loss and propagation distance are the key concerns during data transmission in SDN-enabled underwater wireless sensor networks (UWSNs). In addition, long-distance free-space data transmission in UWSNs relies heavily on FSO communication. Thus, FSO communication is integrated with SDN-enabled UWSNs to maximizing the network lifespan called SDN-enabled free-space optical underwater wireless sensor networks (FSO-UWSNs). Furthermore, clustering and routing can effectively balance the network load for energy-efficient data delivery in SDN-enabled FSO-UWSNs. However, choosing the optimal control nodes (CNs) in clustering is considered as an NP-hard problem. Accordingly, self-adaptive genetic approach-based particle swarm optimization (SAGA-PSO) is proposed as a cluster-based routing to optimize the CNs in heterogeneous SDN-enabled FSO-UWSNs. The proposed hybrid model of metaheuristics and genetic mutation, in which the native PSO is amended with the self-adaptive inertia weights and genetic mutation operation to identify the CNs based on genetic diversity dynamically. In addition, a novel fitness function is proposed to balance the cluster size by considering the most significant parameters like energy and distance of network devices. The SAGA-PSO is simulated using the ns-3 simulator, and SDN policies are controlled via the ONOS controller. Moreover, the proposed nature-inspired SAGA-PSO approach outperforms the existing state of arts by considering the performance metrics such as; alive nodes, stability period, average residual energy, the packet transmitted to CS, average delay, and fitness value.

Published: December 2022

Abstract
Since the last two decades free space optical (FSO) communication transcends the RF communication and microwave systems because of its capability of carrying high bandwidth, license-free, long-range, small size, high bandwidth, low cost and ease of deployment. FSO communication has few limitations as well like beam dispersion, scintillation, weather effects etc. This paper demonstrates the implementation of FSO link and analysis of transmission performance of FSO channel for broadband access networks. The proposed FSO link is simulated in opti-system to analyze the physical characteristics of transmitter and receiver. The transmission performances of FSO link are validated using on/off keying (OOK) and differential phase shift keying (DPSK) at various atmospheric conditions with different data rates and transmission ranges. The transmission performance of the FSO link is analyzed under the influence of key parameters like launch power, beam divergence, atmospheric attenuation, receiver sensitivity and receiver aperture. The proposed model of the FSO link is investigated using key parameters like optical signal to noise ratio (OSNR), noise figure and bit error rate (BER).

Published: December 2022

Abstract
The primary objective of time wavelength-division multiplexing passive optical networks (TWDM-PONs) development at the moment is the cost-effective capacity acquisition. This work addresses this issue by demonstrating a full-system TWDM-PON was selected as a primary choice to NG-PON2 by Full-service access network (FASN) unanimously agreed and International Telecommunication Union-Telecommunication Standardization Sector (ITU-T) G.989. An asymmetric TWDM NG-PON2 was demonstrated that provides 160 Gbps downstream and 80 Gbps upstream which is the target capacity by ITU-T G.989.1 based on OptiSystem-7 software. We propose to use fiber Bragg grating (FBG) and Er-doped fiber amplifier (EDFA) to reduced both of the chromatic dispersion effect and system attenuation until given permission to enhance the distance communication system. The proposed system’s performance is evaluated and compared with other works and ITU-T G.989.2 recommendations to demonstrate how the system can be enhanced in terms of capacity, link distance, bit error rate (BER), Q-factor and receiver sensitivity. According to the results, the optimum possible distance under communication requirements (6 for the Q-factor and 10−9 for the BER) is around 65 km for the system with dispersion compensation. With the help of the low-cost directly modulated laser (DML) for uplink, we successfully improve the power budget to 41.2 dB along 65 km of bidirectional fiber at a 1:512 splitting ratio.
Vaginal progesterone for the prevention of preterm birth: who can benefit and who cannot? Evidence-based recommendations for clinical use
Authors: Conde-Agudelo Agustin , Romero Roberto 
Published: December 2022

Abstract
Vaginal progesterone (VP) has been recommended to prevent preterm birth (PTB) in women at high-risk. However, there is controversy as to whether VP is efficacious in some subsets of high-risk women. In this review, we examined the current best evidence on the efficacy of VP to prevent PTB in several subsets of high-risk women and provided recommendations for its clinical use. Compelling evidence indicates that VP reduces the risk of PTB and improves perinatal outcomes in singleton gestations with a short cervix (≤25 mm), both with and without a history of spontaneous PTB. VP appears promising to reduce the risk of PTB in twin gestations with a short cervix (≤25 mm) and in singleton gestations conceived by assisted reproductive technologies, but further research is needed. There is no convincing evidence that supports prescribing VP to prevent PTB in singleton gestations based solely on the history of spontaneous preterm birth. Persuasive evidence shows that VP does not prevent PTB nor does it improve perinatal outcomes in unselected twin gestations and in singleton gestations with a history of spontaneous PTB and a cervical length >25 mm. There is no evidence supporting the use of VP to prevent PTB in triplet or higher-order multifetal gestations, singleton gestations with a positive fetal fibronectin test and clinical risk factors for PTB, and gestations with congenital uterine anomalies or uterine leiomyoma. In conclusion, current evidence indicates that VP should only be recommended in singleton gestations with a short cervix, regardless of the history of spontaneous PTB.
Influence of production process-induced surface topologies at varying roughness depths on the tribological properties of polyamide steel contact

Published: December 2022

Abstract
Friction and wear in a tribological system are directly dependent on the surface structure and roughness of the friction partners involved. In this article, a clear interaction between surface topologies and their roughness depth was identified for the material pairing polyamide 66 – steel. The typical correlation between roughness and wear, initially decreasing and increasing after a wear minimizing roughness, was found for all surface topologies, albeit at different levels. The effect of the surface topology is negligible at low roughness (S

z
< 2.0 µm) with adhesive wear processes determining the wear behaviour. At higher roughness depths (S

z
> 2.0 µm), the ability of the surface topology to form a stable transfer film determines the tribological behaviour by limiting the effect of abrasive wear processes. A stable transfer film is formed with sufficient roughness and undercuts in the direction of motion, which can be characterised by the average roughness depth, R

z
, in the direction of motion. Based on these empirical results, an explanatory model for the observed behaviour is presented.
Study of molecular interactions of monoethanolamine with some higher alcohols at 298.15 K
Authors: Bhadane Sanjay Jagannath , Patil S. R. 
Published: December 2022

Abstract
Experimental measurements of the viscosity, density, and ultrasonic parameters of monoethanolamine (MEA) with 1-butanol, 1-pentanol, and 1-hexanol were carried out at 298.15 K. The excess molar volume (V
E), viscosity change (Δη), and isentropic compressibility (ΔK
s) are calculated using the viscosity, density, and ultrasonic velocity data. A polynomial equation of the Redlich-Kister type was used to fit these values. With increasing mole fraction, the viscosity, the density and the ultrasonic velocity increase. As the concentration of MEA rises, the excess molar volume falls. All V
E values for MEA and 1-hexanol are positive, meaning that V
E increases. At all concentrations, isentropic compressibility and viscosity change exhibit negative values.

Published: December 2022

AbstractIntraneuronal chloride concentrations ([Cl−]i) decrease during development resulting in a shift from depolarizing to hyperpolarizing GABA responses via chloride-permeable GABAAreceptors. This GABA shift plays a pivotal role in postnatal brain development, and can be strongly influenced by early life experience. Here, we assessed the applicability of the recently developed fluorescent SuperClomeleon (SClm) sensor to examine changes in [Cl−]iusing two-photon microscopy in brain slices. We used SClm mice of both sexes to monitor the developmental decrease in neuronal chloride levels in organotypic hippocampal cultures. We could discern a clear reduction in [Cl−]ibetween dayin vitro(DIV)3 and DIV9 (equivalent to the second postnatal weekin vivo) and a further decrease in some cells until DIV22. In addition, we assessed alterations in [Cl−]iin the medial prefrontal cortex (mPFC) of postnatal day (P)9 male SClm mouse pups after early life stress (ELS). ELS was induced by limiting nesting material between P2 and P9. ELS induced a shift toward higher (i.e., immature) chloride levels in layer 2/3 cells in the mPFC. Although conversion from SClm fluorescence to absolute chloride concentrations proved difficult, our study underscores that the SClm sensor is a powerful tool to measure physiological changes in [Cl−]iin brain slices.
