The Effects of Chronic Inflammatory Disorders and Storage Lesions on Cytokine Levels in Blood Transfusion Productss

Whole blood donated for transfusion is processed into four blood products, namely Red Cell Concentrates (RCCs), Fresh Frozen Plasma, Buffy Coats (BCs), and Platelet Concentrates which are obtained by further processing of BCs. These blood products are then given to vulnerable patient cohorts such as anaemic, cancer or post-operative patients requiring RCCs. However, these blood products may contain biomolecules such as inflammatory mediators that may cause adverse yet often overlooked effects in the recipient. Chronic inflammation is characteristic of numerous diseases such as cardiovascular diseases, cancer, type 2 diabetes, rheumatoid arthritis, inflammatory bowel disease, asthma and psoriasis. Such diseases elevate pro-inflammatory cytokines including Interleukin (IL)-1, IL-6 and Tumour Necrosis Factor (TNF)- alpha in the blood. Moreover, pro-inflammatory cytokines also accumulate in blood products during storage, mainly as a result of damaged leucocytes, and may cause Transfusion-Associated Adverse Reactions (TAARs) and transfusion-induced systemic inflammation. Although this is well-known, very little scientific research has investigated the clinical implications and actual adverse effects these abnormal cytokine levels in blood products from donors with underlying chronic inflammatory diseases have on vulnerable recipients, particularly critically-ill patients who are already prone to inflammation.
Pulsed laser assisted growth of aligned nanowires of WO3: role of interface with substrate

We report here a systematic study of the growth of aligned WO3 (002)-oriented nanowires (NWs) on a (111)-oriented platinised silicon substrate using a pulsed laser deposition (PLD) method. Transmission electron microscopy (TEM) analysis has shown that the wires are single crystalline and grow along the [001]t or [100]t directions. X-ray diffraction (XRD) measurements confirm phase and structural analysis. We investigated the effect of ablated particle flux on nanowire growth, in particular, the role of the nucleating centre at the interface as it gets modified by the ablated particle flux. We observe a critical value of the laser energy (that determines a critical flux and energy of ablated moieties) at which a compact nanograin film gets converted to an aligned nanowire film. We attribute the existence of such a threshold to the desorption process from the catalyst droplet. By cross-sectional TEM and compositional mapping accompanied by simulation, we confirm that the interfacial layer between the substrate and NW is modified by the ablated particle flux and energy. Aligned NWs above the threshold energy can be attributed to the formation of favorable nucleation sites for a preferred orientation.
Ab initio modeling of excitons: from perfect crystals to biomaterials

ABSTRACT Excitons, or coupled electron-hole excitations, are important both for fundamental optical properties of materials as well as and for the functionality of materials in opto-electronic devices. Depending on the material they are created in, excitons can come in many forms, from Wannier–Mott excitons in inorganic semiconductors, to molecular Frenkel or bi-molecular charge-transfer excitons in disordered organic or biological heterostructures. This multitude of materials and exciton types poses tremendous challenges for ab initio modeling. Following a brief overview of typical ab initio techniques, we summarize our recent work based on Many-Body Green’s Functions Theory in the GW approximation and Bethe–Salpeter Equation (BSE) as a method applicable to a wide range of material classes from perfect crystals to disordered materials. In particular, we emphasize the current challenges of embedding this GW-BSE method into multi-method, mixed quantum-classical (QM/MM) models for organic materials and illustrate them with examples from organic photovoltaics and fluorescence spectroscopy. Our perspectives on future studies are also presented. Graphical Abstract
Rancang Bangun Sistem Komunikasi antar UAV untuk Formasi UAV

UAV formation is one of techology development in UAV world. The UAV formation can be utilized in various fields including agriculture, mapping and defense security (HANKAM). Communication is one of the important components in making UAV formations. To make UAV formations, position and direction data (AHRS) from each UAV will be sent to other UAVs so that when forming UAV formation, no collisions occur between UAVs. This study uses a star topology like the one on a computer network. This method involves two or more UAVs, both of which will exchange data. In this study the data sent is in the form of a dummy data package using the xbee module. The purpose of this study is the initial model of communication between UAVs which can later be developed into more complex communication models for many UAVs. The results obtained in the form of maximum communication distance between UAVs is 50m and the recommended optimal distance is 10-20m.

On the family of cubic parabolic polynomials

For a sequence \begin{document}$ (a_n) $\end{document} of complex numbers we consider the cubic parabolic polynomials \begin{document}$ f_n(z) = z^3+a_n z^2+z $\end{document} and the sequence \begin{document}$ (F_n) $\end{document} of iterates \begin{document}$ F_n = f_n\circ\dots\circ f_1 $\end{document} . The Fatou set \begin{document}$ \mathcal{F}_0 $\end{document} is the set of all \begin{document}$ z\in\hat{\mathbb{C}} $\end{document} such that the sequence \begin{document}$ (F_n) $\end{document} is normal. The complement of the Fatou set is called the Julia set and denoted by \begin{document}$ \mathcal{J}_0 $\end{document} . The aim of this paper is to study some properties of \begin{document}$ \mathcal{J}_0 $\end{document} . As a particular case, when the sequence \begin{document}$ (a_n) $\end{document} is constant, \begin{document}$ a_n = a $\end{document} , then the iteration \begin{document}$ F_n $\end{document} becomes the classical iteration \begin{document}$ f^n $\end{document} where \begin{document}$ f(z) = z^3+a z^2+z $\end{document} . The connectedness locus, \begin{document}$ M $\end{document} , is the set of all \begin{document}$ a\in\mathbb{C} $\end{document} such that the Julia set is connected. In this paper we investigate some symmetric properties of \begin{document}$ M $\end{document} as well.
Interpersonal competences of students, their interpersonal relations, and emotional intelligence

BACKGROUND Some of the most important interpersonal competences are: effectiveness in dealing with specific interpersonal challenges and the ability to undertake appropriate actions in a given situation; the range of interpersonal challenges with which one can effectively deal; and satisfaction derived from one’s interpersonal contacts and relations, and from one’s social standing. One’s time at university is one of the most influential educational stages in one’s life and is a time of accumulation of changes related to a variety of dimensions of life. At university, young people, often away from their parents, learn how to be independent, make new friends, and make decisions related to their personal and professional lives. PARTICIPANTS AND PROCEDURE The participants in the study were 173 (92 women and 81 men) psychology students of three universities in Poland who volunteered to complete three questionnaires: the Interpersonal Competence Questionnaire, the Interpersonal Adjective Scales, and the Popular Emotional Intelligence Questionnaire. RESULTS The results showed a positive correlation between the students’ interpersonal competence and emotional intelligence. The research has confirmed the value of the applied methods and the significance of social competences in the development of positive interpersonal relations and the ability to adapt to a new environment. CONCLUSIONS The study confirmed that the interpersonal relations of initiating relationships, negative assertion, self-disclosure, providing emotional support, and conflict resolution positively correlate with the interpersonal relations directed towards cooperation, support, taking initiative, and mutual understanding and that they are also positively interdependent with emotional intelligence of the studied group. One can hope that the confirmed correlations of the students’ interpersonal competences and the kinds of interpersonal connections they establish and emotional intelligence will encourage their social development and future professional activity.
Experimental Studies on Zhenchan Ning for Parkinson's Disease

[ Objective ] To investigate the mechanism of Zhenchan Ning (ZN) for Parkinson's Disease ( PD). [Methods] Rat models of PD were established by striatal infusion of 6-hydroxy dopamine (6-OHDA) . Effect of ZN on rat rotating behavior was observed, and the contents of dopamine ( DA), homovanillic acid (HVA), superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH) and glutathione peroxidase (GSH-PX) in blood and corpus striatum were also detected. [Results] As compared with those before treatment, high-dose ZN could improve the rotating behavior and decrease the rotating frequency ( P 0.05), increase GSH content in blood ( P 0.05) and corpus striatum (P 0.01) and serum GSH-PX activity (P 0.01), decrease MDA content in serum and corpus striatum (P0.01), increase DA content in corpus striatum and reduce the HVA/DA ratio. Low-dose ZN exerted no effect on the rotating behavior, GSH-PX activity, MDA content in striatum, DA and HVA/DA ( P 0.05), but could decrease serum MDA content (P 0.01) and increase striatal GSH content. [Conclusion] ZN can improve the symptoms of PD in a dose-effect manner. Its mechanism may be related to the improvement of bodily and striatal oxidization stress, the protection of neurons and the indirect supplement of striatal DA content.
Assessing the impact of the student voice project on shaping the ethos of Anglican primary schools: a study focusing on the Diocese of Llandaff

ABSTRACT Inspection criteria for schools with a religious character in England and Wales require the sponsoring body to arrange assessment on aspects of the distinctiveness of the school ethos. The Student Voice Project was designed to include year-five and year-six students in this process. Within the Diocese of Llandaff, the Diocesan Director of Education utilised the customised reports prepared at the end of the first year of the survey for schools participating in the project with the senior leadership teams in order to enhance school improvement and effectiveness. The present study compares the responses of the 1,192 students participating in year one of the survey with the responses of the 1,111 students from the same 23 schools participating in year two. These data show a significant overall increase in scores recorded on the six-item scales designed to measure student attitude towards five areas of ethos (school character, school experience, school teachers, relationships in school, and school and environment). These findings suggest that the Student Voice Project, effectively implemented by the Diocesan Director of Education, had significant impact on the participating schools. Similar impact was not found, however, in the control group of students from 41 schools within four other dioceses.
Multimodal Low Resolution Face and Frontal Gait Recognition from Surveillance Video

Biometric identification using surveillance video has attracted the attention of many researchers as it can be applicable not only for robust identification but also personalized activity monitoring. In this paper, we present a novel multimodal recognition system that extracts frontal gait and low-resolution face images from frontal walking surveillance video clips to perform efficient biometric recognition. The proposed study addresses two important issues in surveillance video that did not receive appropriate attention in the past. First, it consolidates the model-free and model-based gait feature extraction approaches to perform robust gait recognition only using the frontal view. Second, it uses a low-resolution face recognition approach which can be trained and tested using low-resolution face information. This eliminates the need for obtaining high-resolution face images to create the gallery, which is required in the majority of low-resolution face recognition techniques. Moreover, the classification accuracy on high-resolution face images is considerably higher. Previous studies on frontal gait recognition incorporate assumptions to approximate the average gait cycle. However, we quantify the gait cycle precisely for each subject using only the frontal gait information. The approaches available in the literature use the high resolution images obtained in a controlled environment to train the recognition system. However, in our proposed system we train the recognition algorithm using the low-resolution face images captured in the unconstrained environment. The proposed system has two components, one is responsible for performing frontal gait recognition and one is responsible for low-resolution face recognition. Later, score level fusion is performed to fuse the results of the frontal gait recognition and the low-resolution face recognition. Experiments conducted on the Face and Ocular Challenge Series (FOCS) dataset resulted in a 93.5% Rank-1 for frontal gait recognition and 82.92% Rank-1 for low-resolution face recognition, respectively. The score level multimodal fusion resulted in 95.9% Rank-1 recognition, which demonstrates the superiority and robustness of the proposed approach.
Design and Experimental Validation of a Single-Stage PV String Inverter with Optimal Number of Interleaved Buck-Boost Cells

Increasing converter power density is a problem of topical interest. This paper discusses an interleaved approach of the efficiency increase in the buck-boost stage of an inverter with unfolding circuit in terms of losses in semiconductors, output voltage ripples and power density. Main trends in the power converter development are reviewed. A losses model was designed and used for the proposed solution to find an optimal number of interleaved cells. It describes static and dynamic losses in semiconductor switches for buck and boost mode. The presented calculation results demonstrate the efficiency of the interleaved approach for photovoltaic system. 1 kW power converter prototype was designed with two parallel dc-dc cells for experimental verification of obtained theoretical results. The experimental results confirm theoretical statements.
Comparative analysis of ageing in Nigeria and United Kingdom using life course approach: the implication for the Nursing profession in Nigeria

The population of Nigerian older persons is expected to reach 26 million by 2050 from 9 million reported in 2016. This population change has several implications, thus the need to pay attention to healthy ageing. Hence, this report aims to compare ageing and its facilitators in Nigeria and the United Kingdom (UK). The life course theory was used to explore the influence of early life factors and experiences on ageing. Unlike the UK, little attention is given to the care of Nigerian older persons. Therefore, Nigerian stakeholders must design and implement a comprehensive policy on healthy ageing. Also, there is an urgent need for training nurses to meet this demand as it arises.
Controlled Growth of Multilayer, Few-Layer, and Single-Layer Graphene on Metal Substrates

The effects of graphene growth parameters on the number of its layers were systematically studied and a new growth mechanism on Cu substrate was thus proposed. Through the investigation of the graphene growth parameters, including growth substrate types, carrier gases, types of carbon sources, growth temperature, growth time, and cooling rates, we found that graphene grows on Cu substrates via a surface-catalyzed process, followed by a templated growth. We can obtain either single layer graphene (SLG) or few-layer graphene (FLG) by suppressing the subsequent templated growth with a low concentration of carbon source gases and a high concentration of H2. Our findings provide important guidance toward the synthesis of large-scale and high-quality FLGs and SLGs. This is expected to widen both the research and applications of graphene.
Cosmic Ether, Possessing Electric-Tension and Magnetic-Resistance, Is the Unified Field for Physics

The paper presents the case that physics is already and effectively unified by the energetic tension field, ether. We identify this integrating power of ether first, by re-defining the action generating parameters of this energetic tension field as the electric-tension, 10 ε − , and the magnetic-resistance, μ 0 , while re-deriving the Maxwell’s wave equation in analogy with the mechanically stretched string, where the . Then, replacing and m 0 by , one can find that almost all working physics theories are being energized by 10 ε − and μ 0 . To complete the unification, we can now postulate that the particles are also freely propagating EM waves, but they are spatially localized as in-phase, close-looped (IP-CL) vortex-like propagation modes of ether. Because of their IP-CL mode structure, they have space-finite spatial structures and remain spatially stationary in the absence of any spatially influencing potential gradients (forces) in their vicinity. Par-ticles’ harmonic phase driven interactions between quantum particles give birth to the appearance of wave-particle duality. There is no need for the confusing and unnecessary de Broglie’s Pilot Wave. The inertia to spatial motion of IP-CL modes automatically accommodates Newton’s laws of motion. The cosmic universality of Maxwellian wave velocity, and particles as IP-CL modes, jointly accommodate the two key postulates of special relativity without the need for unphysical four-dimensionality.
MECHANISMS AND INFLUENCE FACTORS OF DYNAMIC BEHAVIOR OF WATER DROPLETS ON THE COMPOSITE INSULATOR SURFACE UNDER AC ELECTRIC FIELD

The deformation behaviors of a droplet on surface of composite insulator can strengthen local electric field, which could finally lead to flashover. Both experiments and numerical simulations for dynamic behaviors of a droplet on the surface of a composite insulator under applied AC voltage are investigated in this paper. Experiments are performed to study the influences of water droplet’s volume and conductivity on dynamic behaviors. Two critical parameters are proposed to describe the morphological change process of water droplet, and it is shown that the process can be divided into three stages. Moreover, these motion laws are explained by establishing theoretical factors and physical influence models. In addition, we perform computer simulation to study the dynamic behaviors of a water droplet under AC field, and the findings are in good consistency with our experimental results, proving the rationality of the theoretical physical model. It is found that the vibration frequency of droplet changes regularly with at different stages under the AC electric field.
Transient DC Bias Current Reducing for Bidirectional Dual-Active-Bridge DC–DC Converter by Modifying Modulation

Transient dc bias current will appear in dual-active-bridge (DAB) dc–dc converter when power changes, resulting in transformer core saturation. Traditionally, a transitional period with extra calculation is added in the transient process to keep the voltage-second balance and eliminate the dc bias current for the DAB converter. In this article, the modulation process rather than the phase-shift control is concerned, and the transient dc bias current can be reduced or even eliminated by staggering the load time of the primary bridge and secondary bridge compare values. The modulation scheme with this modification does not need any transitional period or extra calculation, and the time delay in the closed-loop control is constant and smaller than the previous schemes. Besides, as only the load time is modified, the modulation scheme can be implemented in all the phase-shift control methods and the whole operation range. The experimental results verify the theoretical analysis and show the practical feasibility of the modified modulation schemes.
The Effect of the Addition of Noni Juice to Seluang Fish Kerupuk on Characteristics and Acceptability

Kerupuk is one of the typical Palembang foods in the form of snacks as a variation in side dishes or as a complement to the main meal. This research is expected to be able to make a new output on the typical Palembang Kerupuk by using seluang fish as a base material and adding nutrient-rich noni fruit. With the existence of noni seluang fish Kerupuk, it is hoped that it can be used as a healthy snack alternative for children and adolescents. This research is an experimental study using a non-factorial completely randomized design (CRD) with 4 treatments and 3 replications. Data collection methods used in this study include organoleptic tests and chemical tests. From the results of the study, it was concluded that the best Kerupuk formula according to the assessment of the organoleptic test was Kerupuk P4 (200 grams of sago flour, 100 grams of fish, 125 ml of noni juice). The results of the proximate analysis of P4 (water content of 6.09%; ash content of 3.28%; fat content of 18.34%; protein content of 5.44% and carbohydrate content of 66.85%). Keywords—Kerupuk, seluang fish, noni, nutrients.
